Here’s what some of our National City, CA customers are saying about us:


The technicians at Underground Autowerks are true 'master mechanics'. Their diagnostic skills are intuitive coupled with great mechanical skills. They displays a deep knowledge of Mercedes and Porsche automobiles. No one else will work on my Porsche GT 3 or Mercedes SL 55. I've been the dealer route and recognize the vastly superior alternative Underground Auto represents.

Rick Brown Underground Autowerks Customer Review


Prompt and reliable service are a key feature of Underground Autowerks. The people there are friendly and courteous, always with a great sense of humor. I like to think I can sneak a free cup of coffee even though I know full well it is free for the taking.

Ron Fulton Underground Autowerks Customer Review


Underground Autowerks did a great job! The best compliment I can give someone is to say I'd love to do business with them again, and I definitely would. Their service was excellent.

Dick Myers Underground Autowerks Customer Review


Underground Autowerks made the whole process very easy, and they deliver more than they promise.

Bob Ramos Underground Autowerks Customer Review


Tim went above and beyond my expectations. He explains with great detail what is wrong with your car and happily shows you in the shop what caused your issues. His work is a reflection of his 20+ years of experience in automotive but his care about his customers exceeds what most can learn in a life time. He is fair and above all, aims to give you the best service possible.

I visited several shops and Underground Autowerks is the only place that aims to save you money and does not upsell anything. My experience with Tim is nothing less than a solid 6 stars. To summarize my experience with him, I called the shop and requested a quote. He jotted down all relevant information regarding the car and would call back. In our second talk, he went out of his way to acquire a unique part I needed, had it shipped from Orange Country and managed to quote me at a little more than half the price of two other shops. He also explained with great detail how my issue arose (something no other shop did) and I happily set up an appointment.

The thing about Underground Autowerks is that it didn't feel like a typical shop where you drop your car off, bend over and take a good one then pay whatever they want before you can say please be gentle. At Underground Autowerks, Tim will ensure you understand all options before proceeding and would aim to give you the best price and best service. Considering he saved me ~1200$, I have no plans of going anywhere else.

I took my car to the Kearny Mesa location for a complete 90K service. Excellent, fast, honest and friendly. I would recommend them to all my friends - and I have.
Tim is a great mechanic. - Thanks

Awesome shop! This is where I take my BMWs and VW for any issues that can be very complicated. Prices are very reasonable, all issues about the car are brought up front and they are provide an outstanding service. Thanks, Tim!

We took my girlfriend's VW Beetle to Tim at Underground Autowerks in National City after taking it to two other places. He diagnosed and fixed a complicated electrical problem right away for a very fair price. Now we call him the Volkswagen whisperer.
Thanks Tim for a job well done!

I waited 2 months before writing this review to see if their work help up.

I purchased a used pick-up and wanted to know what I was getting. These guys were kind enough to see me pretty much right away. They worked the vehicle over and gave me a comprehensive assessment after about 45 minutes.

Two months later, I am extremely pleased that nothing new, weird, or disappointing has come up. They pretty much nailed every little item that I should expect.

At the time, I offered them a tip for their quick and excellent service which they declined - saying it is just how they do business. I figure that if they aren't going to take $$ form me then, the chances that they would try to screw me on service is pretty much zero. I would definitely recommend their services.

This place was awesome!! Had a diagnostic test done and they were honest and up front about the issues on my newly purchased Mercedes. I was able to take the car back to the dealer and use the diagnostic test to help resolve my issues. Thank you for the great service and report!!

Tamisha J. Yelp Review


These guys were great! I had a dead battery on my VW Tiguan on a Saturday and these guys were able to do a 60K inspection and a battery change all without appointment. I got some good tips too about my car and how it compared to other vehicles in its class. So glad i found a mechanic for my VW that is so much cheaper than the dealer!

The techs there are the best. They can solve pretty much any problem that is going on with vehicle. If you want honest and reliable work done on your car, bring it here.

Lee W. Yelp Review


I recently had my vehicle here for brake service and was quite impressed. 1st off the employees were kind and friendly. I was given an honest estimate and was not forced in to purchasing anything. The service was performed in a timely manner and the price was far more competitive than the dealership. I would recommend Underground Auotwerks to friend/family.
