Definately a scam. They got me for $170... and I don't ever even fall for this crap. Until now I guess. They are VERY good at sounding legit. But if you read their refund policy, you realize that it is actually impossible to get a refund. Plus, they WILL NOT sell your car.
I've filed complaints with the BBB and with PayPal. I'm sure nothing will actually be done, cause it's the internet and for some reason we can't seem to actually crack down on blatant fraud on the internet yet. Sad, but true.
