Received a text from (903) 833-4562 within 15 minutes of posting a car for sale on AutoTrader.com.  Here's the text exactly as received:
"Hi,is your Vehicle on Autotrader still for sale?Pls email me at. ([email protected])"
The text was also sent to 4 additional numbers, presumably other AutoTrader listers.  This scam is well documented on this site under a couple of additional phone numbers and additional email addresses.  The followup email from him asked more info about the car, said he'd pay asking price via PayPal and arrange someone else to pick up the car and handle the title paperwork.  It's well documented enough times to believe it is nothing other than a scam.
