Fake Money Used to Purchase Classic Car

Funny you should post this today. I just narrowly avoided being scammed on a modern car purchase after I ran a carfax and realized the odometer was rolled back (note to self: get a carfax before paying for the car). The scammer agreed to void the sale and gave me cash back today since my check had already cleared. I went to my bank with the cash and they scanned it- all was okay and the clerk mentioned that most counterfeit bills they see are motion picture money.
