I dunno, maybe if this were 1988 or something, but I'm not having whack jobs come over to my house over a $1,000 transaction. I'd meet in a well lit public place. I know someone who went to get snows off of craig list and the guy was a g** person looking to pick him up, give me a break.
The other thing is have the seller email a pic--you ought to be able to say turn the rear left and take a pic from the inside with the Michelin at 3 o'clock, and he ought to be able to email a pic right back, instead of downloading images from the web to make you think he has the goods. Lots of predators out there.
