My car was making some unusual either knocking or rattling sound. I called BJ at Dave's early on a Wednesday morning. Since I worked so close to Dave's, they came and picked up my car to diagnose the problem. BJ called/texted me a few hours later. I needed a new catalytic converter. Ugh. The price tag was steep, but when I did some research online, his pricing was right in line with others in the area. They also took care of PSI/emission and did a nice job cleaning up my head lights (getting rid of that fog like appearance on the front). BJ ordered the part on Wednesday. They picked up my car on Thursday, fixed it during my work day, and returned it to my office in pristine condition. Awesome job! Thanks to all at Dave's.
