When I was selling my Audi, I'd have those scam fuckers emailing me everyday saying my client wants to buy your car, yadda yadda yadda. Don't mess with them. Most buyers will be local and you will know if its legit. Don't bother with those sending you checks and having some courier pick it up. The only people I know do that are ones that are throwing $200,000 into a Lambo or Ferrari.
