Joy Auto Service

Koji is everything you want in a mechanic: affordable, friendly, honest, and he gets the job right. I know I'll be a customer for life.

Best mechanic ever. Was introduced to Koji by my parents. He is an amazing, well skilled mechanic who strives hard to give you the best product at an affordable rate.

He's replaced my brakes, rotors, batteries and air filters and I've never had a problem. I'm usually in and out within a couple minutes. He has a small shop but he's very efficient.

I plan on going to him for all my future car needs and I hope he stays in business forever (which is a little selfish of me..).

This is Perla Koji the one with blue Civic Honda....I went to Joy Auto today, Oct. 9 to have my ignition timing set or adjusted by Koji and he is awesome overload! Albert recommended me to him and he was right that Koji is one of THE most nicest and honest, affordable mechanic you'll ever meet in this planet! My only regret is that I should have gone to him ever since I encountered something wrong with my car! A very pleasant, friendly, aside from honest and you can tell he is, they say a picture paints a thousand words & albeit this was my first time for him to service my car, I can tell, I'm going to highly recommend him to friends/family and they would be pleased with him! thank you Koji, keep up the good work! Thanks very very much for accommodating me today! Jeremy S. is right he said "Koji is everything you want in a mechanic"!! i agree 101%!

I called Koji to get work done on a Mercedes Benz and he told me straight up that he could probably do the work, but that he is not a specialist in that car, so he recommended I take my car elsewhere. Five stars for frank honesty and not wasting my time. Three stars for not doing German cars.

Koji is definitely THE most honest mechanic I've ever met. I do not hesitate to take my car to his shop. Completely stress FREE! One time my car broke down in the east bay. I insisted to have my car towed to SF despite the extra cost because I did not want anyone working on my car except Koji. I recommend Joy Auto 110%!!

Koji is the most honest mechanic I know and his shop is the only place I take my car.

Koji works on most cars but his specialty is all brands of Japanese cars. He will patiently listen to the problem with your car and then figure out how to fix it! He is very methodical in his approach and gives you his opinion as to what might be the problem. An honest guy who just happens to be a great mechanic. A rarity these days...Support your local mechanic:)

in my 25+ years of owning cars, koji is the most honest, trustworthy & best mechanic i have ever had (and ive had some shitty cars !).....
