WHAT OUR CUSTOMERS SAY

My wife drove her car up from NJ today, she had already had it looked at in NJ and they replaced the rotors, but the problem was still there as she drove up to Grantham. Since I have my cars serviced at J&S (Jeep and Mercedes--2013) I told my wife to take her Honda CR-V to them. It was late in the day, but they waited for her (Chris and all the guys that work there). They got the Honda up on a lift and narrowed the problem down to two things (driveshaft or bent wheel) in about 5 minutes. I guess the bottom line with J&S is they are there when you need them even though they did not have to be, and they figure the problem out or at least narrow it down pretty quickly. Also, they don't assume what the problem is they actually diagnose it. In this case they would have taken out that drive shaft, driven the car, and determined whether that was the problem. All I can say is that since I have been taking my cars to J&S, and perform the maintenance and service they recommend, knock on wood, I have not had any problems. If I lived in Grantham full time, it is the only place I would take my vehicles, though so far, I plan it so I can have them do the service. , 10/04/2024
