Dietsch Werks

I brought my 1989 BMW e30 here last year for an e36 m3 rack and pinion swap and had a great experience. They really helped me out and had showed me the tie rods on my «new» piece were out. They were able to get me new tie rods at a decent price and the install was super smooth. They also do alignments which I took advantage of. I’d definitely recommend this place for your auto needs!

Rob and Jen do a hell of a job running this shop. Rob picked up and dropped off my car in Walnut Creek at no charge and even gave me a good deal on some parts. His work is top notch and you can really feel that he’s passionate about his work and not only there to make some money off you. He stocks tons of Lotus parts and will give you a great deal.

Wow. Pretty impressed with Rob’s work. Rob and his staff worked on my Delorean. (Wheel balancing and alignment). Now my car drives and handles so much better. Price was absolutely reasonable and work was outstanding.
They have ton of Lotus Elise/​Exige and also some Tesla. I wish I brought my Elise to Rob when I had it. I totally didn’t know he was in Vacaville. Seeing all those Lotus, now I want another one. Rob is going to try to find me an orange Elise or Exige.
I will be brining my BMW and Delorean for more repair.

You will NOT be sorry if you trust Rob and Jen and their crew to work on your Lotus. Rob is fair, knowledgable, and always has kept my car running strong and safe.
I trusted him to do a ton of aftermarket installs on my 2005 Elise, as well as the post warranty work and fluid changes. I can tell you that you will save almost $ 80/​hr for labor charges compared to the dealership and he does not over inflate his work estimates.
The best news for me is that he is now located conveniently in Vacaville, CA. I used to drive down to San Jose to his prior location. The trek was always worth it, but now he’s only 15 minutes from my house. WINNING!!!
Planning on bringing my Evora S for any aftermarket installs as well as any out-​of-​warranty work.

Love this place. Rob helped me out when my car was overheating. He fixed everything within 24 hours and for a great price. I’ll definitely bring my car here again.

I used to work here and I can vouch for their honesty, hard work and knowledge on all cars, let alone Lotus cars. If you have a Lotus this is THE place to go. Your car is very well taken care of and they do what other places won’t do– they educate you on your car with knowledge that can only come from years of experience.

I have been going to Dietsch Werks for almost 10 years. They have moved to a much more massive and convenient location near the airport now. The work has always been great, timely, and prices are fair. Rob is very helpful, friendly, honest, and knowledgeable.

Update #2: My previous update said that I switched to another mechanic in light of the unresponsiveness at Dietsch Werks (despite their high quality work when they are responsive). It turns out that the other mechanic I went to was also fairly unresponsive, so I guess it’s just the nature of the industry and something I’ll just have to work around. I still highly recommend Dietsch Werks.

Rob Rocks hands down. Herb and Jon rock too! These guys know what they’re doing and are the BEST Lotus guys around. Rob is SUPER knowledgable and knows what he’s talking about. He’s always ready to give you expert advice! He’s like a 1−800-lotus help line! He’ll spend the time with you to make sure you know what he’s doing, and WHY he’s doing something with your car. He’ll tell you what you absolutely need and also what would be good for you. He’s fair with prices and always gives you a break whenever he can. He’s taken care of both my Elise and Exige.

Although Dietch Werks is a specialist in Lotus and Deloreans, They also fix other brands. Brought in the Mercedes S500 and it was fixed perfectly at a fraction of the cost that it would have cost to take it to the Mercedes Dealer. Great work done correctly and on time. Doesn’t get any better than that !!!

I had an issue with a vehicle that multiple other shops were unable to fix or insisted would take 25 hrs to complete. Rob’s shop was able to fix the problem within a few hours and saved me thousands of dollars. Not only that but I was extremely stressed about the issue for months bouncing around from shop to shop. I wish I would have just taken it to him in the first place but just didn’t really think about it since my car isn’t quite as exotic as what they specialize in.

Exceptional service for Lotuses! Very trustworthy.
Rob really goes out of his way to help!

Rob Dietsch is an excellent and personable automotive mechanic/​engineer. He methodically checked out the symptoms of my friend’s 1993 Volvo 940. It had major oil leaks, did not run well due to plugged-​up exhaust system and a few minor suspension problems (ball joints, shocks/​struts). The various issues were addressed to get the vehicle operating as a secondary car.
Well, this is the best that the motor has ever ran, the oil leaks were resolved by replacing various seals & gaskets. Unfortunately, oil was leaking from the head & it required servicing. It also easily passed a smog test; not bad for a 19 year old car!
Rob has high integrity & initially goes over everything that needs to be done & also gets the owner’s permission– if he finds other things that have problems. Also, he has no problem showing customers where the problems are located & how they work in the automotive system. All malfunctioning parts were given back upon request.
I’d recommend him & his crew of mechanics to anyone. He is very fair & honest.

There is a reason this shop has all 5 star reviews, save for one «he said she said.» Simply put — they’re extremely honest, offer great service, do quality work and really go above and beyond to make sure you get the setup you’re looking for. On numerous occasions Rob talked me out of VERY expensive parts and modifications — stating for street use they’d be moot. Having owned quite a few cars, many of which exotics and sports cars, this is the best shop i’ve experienced.

I went for some dyno-​tuning after I uprated a cam and wanted to dial in the intake cam timing. As always, great service, great attitude and full data for each dyno pull. I’ll be back when I install the complete Flyin’ Miata 2.5 susension and need full chassis alignment. It’s almost like going on vacation when I get work done here!

These guys are some of the best mechanics around. They have worked on my e30 M3 track car and my DeLorean Time Machine (yes, I have a time machine). The service is fast and responsive, even though DeLorean parts are hard to come by, as any DeLorean owner should know. They fixed the transmission as well as sorted out it’s very complicated electrical system, due to all the props (Flux capacitor and such). Rob even has the shop phone forwarded to his cell so he doesn’t miss a call.
BTW most Delorean owners are never happy (referring to review by R.L.) because the cars are always broken. If you can’t handle that fact, you shouldn’t own a DeLorean.
Just to rebut a previous review, the owner told me that DeLorean service takes a long time and it was a low priority in their shop. I was free to find a different DeLorean expert (there aren’t any). No surprises here:)

I have been searching for an Elise and I had contacted Dietsch Werks about one they were selling, Jenni was quick to point out I should just wait for exactly what I wanted. She invited me to the shop to meet herself and Rob and talk Lotus. Rob spent over a hour explaining what I should look for, what I should have done on any car I decide to buy as well as showed me how to decipher the color codes. They later also provided advice on a car I was looking at. Mind you I purchased nothing and they still were excited to help me out and take time out of their day to educate me on my future car. Rob offered to take me out in one of his cars at a track day or ride along with me and provide some coaching. It is really great finding a garage that is run by awesome people. I look forward to making Dietsch Werks my home garage.

Was having issues with the transaxle in my Porsche, which they diagnosed as needing a clutch replacement. They noticed the clutch slave cylinder was also staring to leak so I had them replace that also while the trans was out. I also had the engine intermediate shaft bearing replaced with an aftermarket piece as preventative maintenence. They did a great job at a competitive price.
Previously I’ve had tires installed and alignments, and they also did a great job with that.

The best service ever from one of the best mechanics on the west coast. These guys are good and trustworthy. You know you will be treated well.

Rob has recently moved to a new location, and has a really nice shop at the Club Autosport venue. I enjoy coming here, because I get to ogle so many exciting cars on the way there and back!
As usual, the service is great and work is thorough.
I switched cars, and Rob took great care in aligning my new beast down to the last tenth of a degree.
Also, when they moved, Dietsch Werks held an open house and I won a free oil change for my car, which I promptly used the very next week! They let the oil drain for a good while, so all the old oil with the accumulated dirt has a chance to come out completely before they fill in the new stuff. I would not expect it any different from Rob, of course.

Rob (the owner) specializes in sports cars with precise settings (Lotus Elise, Exige, 7 and Porsche) and exotics as DeLorean. He vast knowledge on cars also expands to «normal» cars like Volvo and BMW sedans.
Not long ago I sent my car to the shop for alignment work. He set it up perfectly as I wanted (I have a tricky camber setup for track days). That was much better than other shops that are famous for alignment. I also sent my car there for other work and every time it came out great.
Rob is totally enthusiastic about cars. Not only will he explains to you the work he has done, but he will discuss with you any car matter you are interested :)
