Dietsch Motorsports

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.

The most knowledgeable Lotus cars experts in Northern California.  Tremendous expertise in Lotus maintenance and performance.  Happy to answer questions and give guidance.  Highly recommended.

I had to revise this review because, although Rob Dietsch is a great mechanic, the people that are now doing the work at his garage are not (I think they were kids the last time I saw) .

They screwed up on my car and GLUED the broken part back together after torquing the part too hard. I didn't find out about this until I went to the dealership and they showed me the glue from the last attempted maintenance. I ended up having to pay 2k to replace the part.

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.

They charged me a $280 diagnostic fee to find why the check engine light was on and could not find the reason. I brought my Elise to my good friend JJs house and an hour later he found out that it was the coil pack. We changed out the bad one....and guess what? He didn't charge me a red cent. If you claim to be 'experts' at least have a money back guarantee.

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:)

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.

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 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 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.
