A.J. has worked on nearly all my vehicles over the last 9 years, even a back-up camera that my wife didn't like and He took it back, no problem, and we worked out a settlement satisfactory to us both. I my opinion A.J. is a stand-up guy, His goal seems to be to help his customers at the same time, while trying to save them money. But on the other hand He only carries quality products, so nothing is cheap!!
