I love it when you get the email:

"I am interested in buying your (RC car) ......"

The item description is in brackets! The scammers are so obvious.

"Is your item in the ad still for sale?" No, I sold it years ago, that's why I listed it on Craigs to get a check from a scammer. LOL

About a year back, a guy (maybe on here?) had a running email conversation with one of these idiots that went for days! It was priceless.
