Hi, TonyaCallies11. Welcome to the PayPal Community! It's always a good thing to be careful about online purchases, especially when the purchase involves a car!
However, your question does pose a bit of a difficulty to answer directly, but the fact that someone is moving a listing from Craigslist to eBay may actually be a good thing. It's not possible to confirm if the seller is legit or not, as @kernowlass pointed out, but you can find information on common scams at https://www.paypal.com/us/smarthelp/article/scams-on-craigslist-and-other-classifieds-websites-faq30....
It's always good to be careful with any online purchase, but particularly when it involves a large amount of money (which, to some people, might be just $50!). It's also good to acquainted thoroughly with PayPal's and eBay's Buyer Protection Policies.
For PayPal, you can find all the details about the Buyer Protection Policy at https://www.paypal.com/us/webapps/mpp/ua/useragreement-full#purchase-protection. I recommend logging on to your eBay account and checking their Buyer Protection policies. You can also find information by navigating to https://www.paypal.com and clicking Security at the bottom of the page.
I hope this information is helpful, and I hope all your online transactions go smoothly. Thanks for being a part of the PayPal Community!
Sincerely,
Michael
