Customer Review

I have brought only two vehicles into this company for repairs and I am one satisfied customer with both. My first time here was with my 2008 Dodge Charger which went through a flash flood a few years ago and was saved then had a pistol blow through the engine. J & J installed a working refurbished engine which extended my Charger’s years with me. This recent time was a couple of weeks ago where I brought my Ram 1500 with an aftermarket bumper to J & J to see if they can fabricate it on since I ordered it off of Amazon and the bumper was for a Chevy. J & J did one better than welding the bumper on by bolting it in place with bolts they had or ordered. When I got my truck back I was expecting a welding job and a bumper that will have to be sold with the truck when I’m ready to sell. With the bolts, I can now take the bumper off if needed. J & J saved me a lot of stress and time with both my vehicles. They have so much knowledge with any vehicle and respect with their customers along with amazing service.

These are the guys to go to--trust me!!!! You want quality work done on your car, these are your guys! Javier and Jesus are not only excellent experienced mechanics, they are also very humble, very friendly hard working gentlemen that make you feel welcomed and treat you like a family, we will not go to anyone else for auto repair, they have been servicing our vehicles for many years they are knowledgeable, professional and trustworthy and their prices are reasonable. - Alejandra R.

Arrived here disgruntled after Normandin Chryslerjeep wanted $190 and a week's time just to diagnose transmission on my Fiat500l. Amazingly it's fixed by J&J for $100 in 3 hours, including the parking light bulb that needed replacing! Moved by the honest straight up approach and highly recommend this business. They work on all brands and I saw some fancy vintage wheels too. Special thank you to Jesus and team. - 5 star review on Google
