Auto repair and performance work for daily, weekend, and track cars in Concord

“Had my Macan Turbo serviced by David today for the first time for multiple drivetrain fluid maintenance items and a control arm replacement. This is the kind of auto shop I like to work on my car, finally, I found one and that works alone focusing on my car's requirement until it's professionally and thoroughly fixed. The shop has complete tools and equipment to boot, spacious, uncluttered too.<br><br>Unlike other too busy shops that have mechanics doing multiple work at the same time and most probably make some missteps along the way (dealers included). I find David as a highly experienced automotive professional who I learned was in the field of teaching, training, racing, and rare vintage cars restoration industry. Car enthusiast shop/place for sure.<br><br>By the way, my car now feels like brand new again! Thanks David it really did made a difference!”

“Dave is a consummate professional and an absolute master of his craft. He knows absolutely everything about cars, and you can tell right away you’re in good hands.<br><br>He’s a great communicator, which is rare.

Honest, thorough, easy to deal with, and clearly takes pride in doing things properly.<br><br>100% recommend his work to anyone.”

“Dave is a master mechanic! His experience and talent truly stand out. He takes great care of my car and always ensures everything is done perfectly. He’s also very kind and generous, taking the time to explain every step of the process to me. Every time I’ve brought my car in, he’s fixed it up quickly and kept me updated throughout. I always trust him with my car, and if anything ever happens, I know it’s in the best hands. Highly recommend!”

“I can't thank Workshop D enough for the amazing service I received today! My good friend Dave helped me out with an oil change and a few other things on my Mitsubishi Evo. His honesty, expertise, and professionalism really stand out. The shop is absolutely top-tier, well-organized, and clearly run with a lot of pride. If you're looking for reliable and trustworthy service, I would very highly recommend Workshop D! I'll definitely be back!”

“Truly Amazed! David is a thorough professional and a gentleman! Took my Tesla Model Y for wheel bearing replacement. The part was in very short supply, yet he was able to secure them via his connections at Tesla. He did an excellent job with replacing the wheel bearing, and cherry on top he also washed the car once the job was done. Extremely happy to have found such an excellent mechanic in my area!”

“The best mechanic I've ever worked with. He is incredibly knowledgeable and will treat your car like its his own. I had him replace the turbo on my Mk7 Golf R and the throughout the entire process I was constantly updated and informed on what was being done. No issues after the install. He set up the alignment after I installed coilovers and the car drives amazing now. Thanks Dave!”

“David did an excellent job doing a full corner balance & alignment on my M3 to prepare it for an HPDE event. The car felt like it was on rails at the track, David’s experience as a race team mechanic truly shows through. Also a great shop for pre-track day inspections (as required by BMW CCA or PCA). Highly recommend Workshop D for performance work or routine maintenance!”

“Took my car to Mr. David Lee (the owner) at his Workshop D as it was driving a bit rough, he took it for a spin and pointed out what the issue was and adjusted to 100% accuracy. Can’t be any more happier. Very knowledgeable and learned so much just by talking to him, extremely satisfied, recommend to anyone whether it is your daily, weekend or your track car.”

“David's attention to detail and communication are fantastic; he could teach a course in how customer service should be done. He documented and photo'd every step of a suspension kit install with ample notes to fully understand every setting and component. He was highly recommended by numerous friends and I can see why.”

“Dave is an absolute master at his craft. I really love his attention to details, patience to educate his client and totally honest at his work.<br><br>I am so glad to get acquainted, he was referred by close friends in the business. Definitely my go to technician/mechanic for my ducs!”
