Electrical repair service near Diamond Bar, CA

Professional/excellent service. I would definitely recommend this auto repair shop to others!

one of the worst feelings as a car owner is when that red "check engine" light appears...ugh. i brought my truck in today knowing that robert & his crew would be honest with me and let me know if any repairs were truly needed. i feared it was my alternator, a very costly repair... turns out it wasnt, and was related to the ignition box which has been replaced earlier that morning. no repairs were needed! big sigh of relief! i continue to give this business my loyalty because i trust them. bonus is that you get a complimentary car wash with your service. win! win! thank you again silver star !!!

Alvin and Paulo are definitely one of a kind. I originally went here for an oil change as yelp had great reviews regarding their service and specializing in Mini's and BMW's. The reviews are true and they provide great service and treat all their customers with integrity. They are not a shop that will tell you your car needs service just to make a buck. They are straight forward and honest in what your car may need and leave the decision up to you. Recently I unfortunately had my Water pump go out. I called A's Garage right away and Alvin stayed after hours to receive my car from the tow truck and even gave me a lift home. Can't say may places would do that. This shop has won me over and this will be where I will surely get all my services from, from now on.

Great job! Fixed an ongoing problem with my brakes at a good price. Honest, same-day service.

Owners, chief mechanic Chris is a native of Sweeden where he learned from the Volvo factory the highly technical applications of diagnostic techniques fixing Volvo automotive as well as the Saabs. Chris & his parents including cousin Jim worked at the Volvo factory. The mechanics working at Bertone has one common goal, customer satisfaction. None can compete with Bertone with consistent top quality service with very reasonable price. Bertone's customer base is built from repeat customers & referrals. Roger Valencia
