I guess I was lucky with mine, I kept an eye on it in autotrader for months as it was overpriced, dropped by 5k so I gave them a bell on a Monday or Tuesday. Salesman said you are the first to call, he gave me a brief description which was immaculate and said I could have the first test drive, no commitment needed but I had first dibs.
Turned up on the Saturday after a 2 hour drive and there she was, immaculate as he had described. Nice test drive and a thorough going over and she was mine. I guess I was lucky and the salesmen trusted clients and knew how to deal with customers.
Hope you find a gem too.
