I've sold 3 vehicles(Suburban,Toyota Previa, M-B ML-320) plus a motorcycle. No issues.
The Suburban ended up being local, he was as scared as I was, but I had my conceal carry and was packing for the tranaction. We met at Target, he gave me remaining money, I signed title and he drove home.
The Previa ended up being semi local. I ended up driving the vehicle to pick up the new owners at the train station. They drove the Van 3.5 hours home.
On the M-B ML-320. We had some issue with money transfer, but I stated that I would not release the vehicle unless the funds showed up in my bank. and at the last hour before the 18 wheeler came to pick it up. the funds were transfered. Funny that the owner didn't really care about title on this. When the truck company came to pick up vehicle, I asked why, the truck driver said that the vehicle is on its way to the dock to a Eastern European country.
Always request deposit based on vehicle cost.
