You had to have an SCCA license to buy those ACR Neons. I was very unaware of that. Had a customer come in with one, he would complain of of a "vibration at speed". We couldn't duplicate the problem. He came to get the car close to closing time, it was my late night so I delivered the car from service. He was back within 20 mins complaining the vibration was still there. He insisted I go for a ride with him so I could feel what he was talking about. We got out on I-275 and that's where things got hairy. Oh, there was a vibration all right and his definition of "at speed" was 95 mph. That ride scared the hell out of me!! That customer raised 9 kinds of hell because we missed such an obvious vibration! There was no way our techs were going to test drive a car that fast. I think we replaced the struts but told him that we weren't driving the car the way he did. After that, I stick to the parts dept. no more customer rides!
