Got the same text as everyone else here just now saying they are willing to buy my car in its condition sight unseen. They request I get a PayPal account so they can pay me right away. Sounds fishy. I would suggest to be aware and don't go for it.
You are correct to ignore these type of messages. The next step would be to send you a fake but legit looking PayPal payment notice for more than the actual purchase amount with instructions to wire the excess to his "shipper" or "mover". If you go to the real PayPal site and check your account you would see that no funds were deposited. If you point that out to them they will claim the funds are being held pending you wiring the shippers fee then the money would be released to your account. Text back, in person sale only, cash or check with 2 forms of ID.
