Concept 3

Totally over rated !!!
Very un professional cannot even quote for basic upgrade on a new car leave alone anything big. Seems very arrogant and no return emails and phone calls. Dont have guts to even come to the phone and talk. The girl on the phone was shielding him behind.
Come on act like a man.
Wish can give minus 5 zero.

Read lot of reviews and knew people who got work done here so I knew what to expect. Came here multiple times for different parts to be installed. Came in the first time for full LED headlight, DRL, and fog installation and ended up buying a cold air intake as well. Will the owner of the business waived the installation for the cold air intake and part the LED installation as well. Took maybe 1.5hr to install, test, and put back everything.
Came back couple of times for coil over installation which they offer you a lifetime adjustment with them.
Had issues with the LED but that was the manufacturer problem and Will always replaced it no question asked and even went as far as to replace the entire LED with the new manufacturer he moved to as well.
Overall great place for your KDM needs but make sure to call ahead and make an appointment since there’s always cars being worked on in the garage.

Great products horrible business. The owner Will is very crispy and doesn’t understand customer service. I purchased the bt1 plug and play and I needed to get it taken off before taking my car to the dealership and he wouldn’t call me back to remove it. So I stopped by in the morning when they first opened so I could have him remove it however he handed me a pair of pliers and said «remove the zip ties, the rest is self explanatory»… Are you fucking kidding me. I didn’t want to deal with him so I tried doing it on my own only and got so far before I didn’t know what to do. I asked him if he would guide me through the rest of the process and he just acted as if I were stupid and said «its very simple, but I won’t be able to get your car in until 1». And it was 10:30. Fuck you dude honestly. So dam rude, if it’s that dam simple just be a good business owner and take care of your customer and I’ll be out of your hair. So turned off by this guy. Idk what I’m going to do when I need to get the device put back on. This place is a stressful experience.

So I found this place because the shop that I went to first was shitty (modbargains). The «modification expert» at the said shop told me that what I wanted to do on my frs was hard and it’ll take so and so amount of hours to do it and it’ll cost a lot. So in short the dude was fucking lazy. He even told me to go to his buddy’s shop which was in chino and is like a 30 min more drive. So I didn’t listen to him and just looked around and thank god I found this place. The guy was pretty professional and even recommended some other stuff for my car (scion frs). He was able to do what I planned on my car and make it even better. I honestly don’t know why this shop is getting bad reviews from other customers. I left my car in the shop because I don’t want to rush the guy working on it and it was worth it. I’m definitely going back to this shop to take care of some other future mods that i will be doing on my car.

«Dont trust this business, Poor experience!!» We drove approximately 80 mile to have an audio instalation done. I called 10am & was invited to bring my car in for the service by Gracie or Grace. We arrived at 12:30pm & they did not perform the installation. They wanted to reschedule for the next day. I explained the effort and distance we made to drive there. They didn’t seem to care, unapologetic!
— How can you trust people who conduct business like this???

It’s my second time to write a review on Unilocal.But, this time is a good one. Will is a very nice guy and professional to car modifications. I brought my minivan to have coilover installed. It came out so nice and dropped my sienna from sky to ground;)
If you looking for a excellent job done at fairly price, then you should visit here.

Shop owner is lazy, cannot find a more tentative scheduled place than this.
Labor is cheap but you get what you pay for, customer service is horrible
Also after doing an air suspension install here, my bag popped 2 months after.
You have your warning

Very popular shop. Will is very knowledgeable.
Appointment is a must. May be a long wait to come in but totally worth it.

DO NOT GO HERE. THIS IS THE WARNING I NEVER GOT.
Don’t believe the hype. Any positive reviews gotta be either: his friends, paid for, or people who might actually be happy, but with a super simple job even a brain-​damaged monkey can do.
This guy is as rude as he is inept. Total drama queen. Terrible work, terrible customer service. Major ego issues. Total joke.
On my brother’s car:
— he put the wrong sub speaker in (my old one, i had to remove it later myself).
— left iphone cable hanging out in a terrible unprofessional way. Didn’t mount it as requested.
— used a bad backup camera where he had to drill holes into the metal of the trunk, and the cheap screws came out within a week, leaving the camera dangling.
There are plate-​mount bar-​cams, as well as replacement trunk latches with cameras built in (both OEM and aftermarket), that would have been much better, & also mount on-​center, rather than awkwardly off-​center, on the right side of the latch. Annoying af.
My car:
— He lost my $ 30 iphone cable
— denied ever being given it
— left black handprints all over the headliner material on the pillar between the windshield & driver window. This guy can’t even wash his hands.
— left HDMI cable plugged in when I asked for it to be removed
— threw a tantrum when i simply asked for it to be removed. Really? how hard is it to pull a cable?
— connected the antenna cable to the wrong wire, so no radio functionality.
— ruined the clips around the trunk arm, leaving the plastic cover unfastened
— ran backup cam cable janky-​ass way, pinched through the seam between license plate LED assembly & the metal of the trunk, when he could have drilled through an unused bottom license plate screw hole (plastic blank inside, no puncturing of metal or pinching of cam cable required).
— installed my backup camera with the cable so tight it came loose inside the trunk lid & i thought my camera was dead. it was only after removing the inside trunk panel myself after weeks of no camera that i saw how unnecessarily tight everything was & that the power cable had disconnected due to the tension (it’s just a barrel plug!)
— refused to finish my car — what was left: to install the bypass cable he failed to have ordered in time before /​remove the HDMI cable hanging from the steering column.
Worse than his work is his attitude & customer service. In his mind, the customer is always an idiot and an asshole, and he is a genius and a tough guy.
Nevermind that he’s not even good at what he does. He did a terrible job on our cars, as listed above.
His front desk people are nice enough & try to help, but relaying messages to him via them is a bad idea. It’s not their fault; they relay a message, but then he flips out and throws a fit in the back of his shop like the drama queen he is, to impress his employees & friends that always loiter about, to show what a ‘tough guy’ he is. You can see & hear him do this. It’s amazing. He does this every single time you communicate to him via employees, without fail. It’s better to just communicate with him directly, as his ego isn’t prone to such histrionics without an audience, as well as having to talk to you face-​to-​face.
Because he didn’t have, let alone install, the bypass cable the first time, I had to come back. I missed the appointment twice for 2 reasons: 1) medical, and 2) his receptionist decided the earliest time and didn’t tell me that i could have come later in the day. That wouldn’t have been a big deal had i been able to reschedule, except, because I didn’t bring my car to do the 10-​minute job that it would have taken, he flipped out and refused to finish it, handing me the bypass cable to install myself. He didn’t refund me a penny for the services promised but not rendered.
Yesterday I went to a new shop a few blocks over, where Advantage Audio used to be, on Lambert, & those guys were really nice. For $ 45, the guy:
— installed the bypass that Will refused to install
— removed the HDMI cable Will refused to remove
— connected the antenna cable Will improperly installed to the correct wire.
— replaced the bad iphone cable
— installed an aux adapter cable i had
i didn’t think Will had even installed the radio antenna (it wouldn’t have surprised me a bit considering his disregard for his work or the customer), but this guy showed me that he did, but just connected it to the wrong cable entirely. Once connected to the correct cable, I could hear radio stations very well. 8 months after Will should have done it correctly.
I shouldn’t have had to pay somebody else to fix everything but I didn’t want Will touching my car again, nor did I want to deal with his acrimonious demeanor & infantile behavior. I also wanted somebody to give it a good look-​through & properly diagnose the problems I was having (iphone no longer connecting, backup cam no longer working, no radio reception at all), before taking it to Will, so I’d know what i was dealing with.

I was referred here by a friend. Awesome shop. Highly recommend.

I’m super happy with the work that was done on my car from Concept 3. They explained everything to me from start to finish. My car was done in a timely fashion. I will definitely be going back to these guys next time.

I recently had an igniter go out on the Drivers Side HID, on My 2015 Genesis 3.8 Sedan, which was newly installed in Feb-​Mar 2015 of this Year. So After I called on Concept 3 on Saturday, to have them address the issue. Will replaced My 6K Bulbs with 5K to see if I’d like them. So when I finally pulled into My Garage I noticed on the My Garage Wall that the Light Placement was off and Yellowish at the Top. That Evening and On SUNDAY, I called TWICE and Left 2 Detailed Messages to See if I could do a Stop By and Have Him address it. They Made time for Me and Fixed the Problem, it was just a minor adjustment! I like the the 5k, but not sure yet. Thanks CONCEPT 3, You’re the Best!

Excellent service, extremely friendly employees. Will, the owner, is very knowledgable about Kia’s and Hyundai’s. Even though I brought him a Volkswagen he still knew everything about the car. The receptionists are also very friendly. Great shop! Definitely recommend this place for all auto needs!

If you want to have any parts installed into your car or have any questions at all regarding your car, this is the place for you. Will is a genius when it comes to cars and he does an amazing job! Plus he’s very friendly and easy to get along with. I’ve been coming here the past few years and left satisfied every time.

Hands down one of the greatest customer service ive had in awhile. Brought in my headlights and they had me in and out in about 40 minutes! I’d defiantly recommend anyone who wants to make adjusts, small or big to come here and at least check them out. Not only are they great with customer service but they’re knowledge about cars is phenomenal!

I’m so glad I found this place. Normally they shops assume no one knows anything about cars but their techs. They try to skimp you and juice money out of you.
He made sure I was happy with my car and everything I needed done to it was very well done and professional.
The owner, Will I think, definitely knows what he’s doing and I would highly recommend this place ^.^
He does everything from general maintainence to cosmetics and customizing.
And also, one last pointer… his car is sooo sexy

Worst place to buy parts, rip off. Buy your hid/​led etc at DDM tuning. Overpriced. Wish I could give a 0. Not worth the drive. They wanted $ 75 dollars to remove the bumper to install hid

Great service and very knowledgeable staff!
So I like fast cars! I love the adrenaline rush when try to break the speed of sound, ok maybe not. So recently got a little 2 door «speed racer», and the 1^st week I got the car, I got a speeding ticket in it. Obviously I figured out that I NEED to get a radar detector installed, so I called these guys. The guy that picked up my call was super nice, and super knowledgeable and spent quite some time on the phone with me explaining to me what kind of radar detector I needed an how much they cost and what accessories I also need to purchase. He also told me they are able and willing to hardwire it into the car for me and place it so the cops wont see them. They are legal to have by the way!
I ended up giving the car to another family member due to the seats being uncomfortable but will be purchasing another «speed racer» soon, and when I get it, I will definitely take it to these guys to get my «cop detector» installed!

Honest polite guys that provide free estimates and fair prices.
The only reason that Concept 3 gets 4 stars instead of 5 stars is that they don’t check their answering machine very often. I would highly recommend calling back later instead of leaving a voice mail.
You should definitely make an appointment as they are pretty busy and have customers dropping in all the time.

Great auto shop for all kinds of cars! They specialize in KDM cars but are also excellent with many other cars like Honda.
The owner, Will, knows everything there is to know about cars and does great work!
Many friendly customers daily and also great customer service!
Stop by when you can, you won’t regret!
