Alex the owner is amazing!!!! What the dealership was charging me $300 he didn’t way less than that!!! My truck is running super smooth, great shape! Very honest! Love! Love them!
Happy Karz: A Very Rare Find
A very rare find: honest and very competent mechanics who charge very fair prices! I would heartily recommend this business to all my friends.
Happy With The Service
They are very professional and cautious. I think also they are very knowledgeable. The price tag well high but worth the quality service they provide; could be lower some-worth.
Wouldn’t Put My Car On Anybody Else’s Hands
Wouldn’t put my car on anybody else’s hands. These guys truly know what they’re doing. They don’t try to deceive you and overcharge you for unnecessary “repairs” and get the job done in a timely manner! Do not hesitate to go there, You and your car won’t be disappointed.

Great, Fast, Service!
Alex got my oil changed in about 15-20 minutes and let me know of a few other repairs I should make soon. These guys are a NO BS shop and won’t rip you off.
