The Becker Silverstone CD changer was made by Sony. The problem with these changers appears to have been the more complicated cassettes supplied by Mercedes. I've had a reconditioned unit for a few years and use simple Sony cassettes in it that do not bind/jam. I've never had the slightest problem.

I also feel that it's not fair to judge the quality of a vehicle that's been used and abused by someone else before you get it.

As an example, I have two neighbors who each own a Lexus. One of them does his own maintenance and gives his cars tender loving care. The other one has his car serviced at Walmart, uses cheap high sulfur fuel and has it washed in brush type car washes.
