Old guy calls: COME get this car junk outta my garage!

I sold the guy a fender last year and he remembered me. He is a sorta private guy and didn't want a bunch of craigslist strangers coming by his house.

When I sell at swap meets, I try to engage the customers by being friendly and asking about their projects. I've sold stuff weeks and months later because of treating people like friends.
A buddy of mine has also sold stuff at swaps but always comes off as gruff and introverted. He never seems to sell much.
