Was recommended to come here this morning by Nolan’s Auto Service since they get all their alignments done by Sal’s and they aligned my car in less than 45 minutes! Really affordable and fair price and Mr.Sal just looks like a trustworthy man- which matters when you’re a girl cause so many places always try to scam us. Thanks Tio Sal!

5-star review by Valery Bazooka

Professional, quick, and considerate. Their attention to detail and making sure you have good tire pressure make them stand out. Their prices are hard to beat. Highly recommend going to them.

5-star review by Luis Ravas

While looking for a mechanic I honestly prayed to God that I would find a semi honest one in my area and once I met Sal I knew what his intentions were. He's an honest guy, doesn't beat around the bush and tells you from the beginning what is required of him to fix your vehicle. I recommend him 100%!

5-star review by Brayaan Castaneda

Sal is a great mechanic. He has serviced my Sister's cars for many years. Then I finally tried him. He is wonderful. He takes care of issues you have. Then he let's you know if there is something else to be taken care of, within time. He never pushes. Thanks. Sal.

5-star review by Bunny Bashford

Took the car in to check the CV axel and he inspected the brakes, rotated tires, added air, and gave us advice for the axel and only charged for the rotation of the tires. I feel good knowing that if my son hasany issues with his car he can always count on Sal's.
