Brought my Jeep Cherokee XJ in for a complete 4.0L engine replacement. They're a certified Jasper vendor and managed the whole process smoothly from start to finish. What really impressed me was they also diagnosed some electrical issues I suspected but didn't know how to fix. They called and explained what they found, then asked what I wanted to do about it before doing any work. That kind of communication and honesty is hard to find. The quality of work was excellent. Trustworthy mechanics who know what they're doing. I'll definitely come back for any major work. Highly recommend for serious mechanical work.
Jesus was great to work with. Knowledgeable and quick to found out the problem on transmission. Thank you, again
I recently had the pleasure of working with J and J Auto Service for repairs on my 2007 BMW, and I cannot recommend them highly enough! From start to finish, their team was professional, knowledgeable, and incredibly efficient. They took the time to explain the issues with my car in a way that was easy to understand, and they provided clear, upfront pricing with no hidden fees. What really stood out to me was how quick and flexible they were. I needed the repairs done as soon as possible, and they went above and beyond to accommodate my schedule. The quality of their work was outstanding—my BMW is running better than ever, and I feel confident knowing it was in such capable hands. I would absolutely recommend J and J Auto Service to all my family and friends. If you’re looking for a trustworthy, skilled, and customer-focused mechanic, this is the place to go. Thank you, J and J Auto Service, for your exceptional service—you’ve earned a loyal customer for life!
My Toyota mileage recently getting lower I suspect it need a diagnosis. I bought my car to them. Javier one of the guy who run this shop listened my description, he told my first resets all the reading then run for a week to see if the same reading still consistent, then he will perform a computer diagnostic. Honesty is the reason I go back to this shop. Way to go
