Omar and Kathy were very helpful. The price was reasonable was hoping to get the military discount but supposedly don’t give out 2 discounts at the same time.

I love J-n-J

Jim and Kathy are the best!! They are always professional and considerate. They always make room for me because I have a crazy schedule and it’s hard to make appts. Omar is my favorite … More technician. He always takes care of my car with care (and never complains about it being filthy). Less

What impressed me the most was longevity of the … More business. I know he’s doing integrity work to be in business this long. Nice shop and facilities. I do plan on using them for future repairs.
