I placed a $500 deposit on a used BMW being sold by Alan Byer over the phone, shortly before they closed for the night. This deposit was verbally made conditional on my complete satisfaction with the condition and quality of the vehicle, since I had at the time only seen it online. The salesperson assured me multiple times that I would be refunded and not be obligated to go through with the purchase should I discover that it's not in the condition I expected. He stressed that they were a "very professional" dealership who would make sure I was satisfied. I did not sign anything.
The next morning, I asked the service department of a local BMW dealership to look up the vehicle's maintenance history and discovered a number of serious problems including a piston seizing in the engine and the complete failure of the clutch along with numerous other leaks throughout the vehicle's history. These have since been repaired, but all of this was highly abnormal for a vehicle of this age and mileage, which led me to think that the vehicle had been abused or problematic to start with. This made me dissatisfied with the condition of the vehicle, so I contacted them the following morning to inform them of my decision not to proceed.
However, I was still charged for the deposit and I contacted my salesperson to refund it. After not hearing back from him, I ended up filing a dispute through my credit card. Once they received the chargeback notice, a manager there called me to apologize for the mistake as he claimed that they did not realize that the money was never refunded to me. He was understanding and stated that it was a simple oversight on my part, and that he was sorry I had to go through the trouble. In the end, it all worked out -- they sold the car to another buyer, I bought another new car with lower mileage, and they made right on my deposit. Water under the bridge, I suppose.
