Craig's list, is it a safe place to sell?

[GMC AMI]

I recently posted one of my trucks for sale on the Maine Craig's list and what a lot of spammers. Here is one of the e-mails sent me

"I am interested, can i trust you,i'm a navy captain working on ship
and I'm offering additional $100 to your final price for you to keep
it off from other offer.could you please provide me with recent
pictures of this item so i can see the condition before we proceed and
Also,i'll be paying you from my paypal account, so if you are still
okay in selling it off to me, kindly get back to me with your name and
paypal email ID so i can send the money as soon as i have your paypal
info. so i can make the payment asap for the item and if you don't
have paypal account yet, it is very easy to set up, go to
http://www.paypal.com and get it set up.. looking forward to your
response.

Regards.

Brett

You really have to wonder is this for real? Has anyone heard of a scam with Paypal? Posting PICS of truck, note not for sale on this board. No one would drive this far north. Here is a copy of my ad.
