My first car ever was a 1986 BMW 528e. I got it without ever seeing the owner. It was apparently owned by a high school kid, and he left the keys in the car for us to look through it and drive it (!). I offered him 400 dollars over the phone and he said to leave the cash in the mailbox (!!). The title was already signed over in the glove box. The car itself turned out to be completely fine, aside from a ton of rust under the rear bumper, which I took off and replaced with that fiberglass you soak in glue, like a real expert. I sold it about a year later for $1200. It was a good car, but I probably should have been more suspicious about how it was being sold.
