Its unfortunate, but several members have had their fingers burned through scammers, so if in doubt its always easier to sell to someone with history.
I have once sold a car to a new member (on another forum), then received an email telling me it had some marks on the underside of the chassis, even though it was described as having run two seasons outdoors with usual wear and tear! The guy was new to RC and didn't quite understand what normal use can do to a chassis and so I wished I had sold to someone more experienced!
Guess what I am saying is, that due to a few bas experiences, honest buyers are sometimes penalised, so don't take it personally and I am sure you will find something!
