shouldn't have done this...

I'm not street wise enough to do this selling on Craigs list thing. Just got this email: "Hello, I am interested in purchasing your car posted on craigslist,I will pay $1600 for it and i am willing to purchase it as soon as possible. Get back to me immediately if the car is still available for sale. Thanks" Pardon me for being a little skeptic but, who buys a car sight unseen and offers more than the asking price esp for OBO situation. No name, just "thanks" and doesn't even want more details. UGH! This is too stressful for me!
