Take a deep breath and think about this folks. Unless you have never purchased or sold a home, car, boat, RV, motorcycle, four wheeler, or large appliance and never plan to do so for the remainder of your lives you'll have to get over your mistrust. You can't go through life with a cardboard box full of paper currency changing hands .
The EFT or paper check offered by VW is the way the world transacts business. You'll walk away from the turnover transaction with either a paper check which for the skeptics could be bogus and a receipt signed by a VWAG representative proving VW took possession of your car.
If the check bounces or the EFT doesn't occur as promised it wouldn't take 15 minutes to find a lawyer happy to file a lawsuit against VWAG on your behalf.
