Been working on this 1997 Wrangler taking up drive way space for several years. Getting parts from junk yards, Craig's Lists etc. I've watched many "How To" Tube videos and purchased tools and testers to make it road legal. Finally, taking it to Mastertech. They solved the problems and it passed the smog test.

I'm super happy with the service I received here. They were able to diagnose a suspension issue that another mechanic did not catch. They got the parts ordered quickly and had my car back to me promptly. I was also so pleased that I ended up paying less than the price they initially quoted since they later found that some of the work they planned to do was unnecessary. I'm so glad to have found an honest, transparent, and knowledgeable repair shop.

I have a 2000 Ford E350 4x4 with a 2010 F350 front axle & transfer case. There is also 2008 E350 steering components. I am the 4th owner. All the work was done before me.Master Tech took approximately 4 days to do the alignment in which they found a bad tie rod and a steering pittman arm. They had to figure out what year the parts were from but after a few days yesterday's the van drove like a dream. I highly recommend this place.

Mastertech took on the assignment of completely going through our 1956 Corvette to assure that it was in perfect condition in preparation to sell it through an auction. They did an excellent job of checking every detail of this very special car, and tweaking and correcting a few things that needed attention. The shop was clean, and the technicians were very knowledgeable -- we couldn't have found a better shop to accomplish this daunting task. Special thanks to Rick and Bob! Well done!

Bob is incredible! I took my car in after being quoted an absurd amount at various other repair centers and he was so nice and made me feel very taken care of. He got to the route of the problem much, much quicker than I could’ve imagined and handled everything in such a professional manner. He is one of the nicest men I have had the pleasure of working with and highly recommend his services!

I brought my daughter's Elantra in for an AC service, and was pleasantly surprised from the initial phone call with Bob, to my final conversation with him when he gave me the bill. He quoted me a very reasonable price to diagnose and fill with freon, and kept to his word when all said and done. He also completed in the same day with no surprise issues! I had called Hyundai in Carlsbad to get it serviced there, but they were months out. I appreciate Bob's professional and delightful demeanor, and I can say he has earned my trust and continued business. Thanks Bob and service team at Mastertech!

Rick and Lou are some of the most knowledgeable mechanics in the industry. Book ahead because they are fairly busy. Not the cheapest but the best.
