I got this message from eBay after I hit the "ask seller a question" button and asked if I could send someone to have a look at the car.
Dear grandpadodge (regoevans@sbcglobal.net):
Our records indicate that you recently sent an email to or received an email from weesone through the eBay email system (for example, you may have sent an email to this member through Ask Seller a Question or received an email from this member through Contact eBay Member).
Sometimes eBay accounts are used to send email solicitations for transactions outside of eBay, or to send unrelated questions in hopes that you will respond so that the other party can obtain your email address. We wanted you to be aware of the potential fraud risk these solicitations pose and encourage you to be cautious about the email you received from this member.
Please keep in mind, sales that take place outside of eBay are not eligible for any eBay or PayPal protective services and you run the risk of losing your money or your item if you complete these transactions. We would encourage you to review the eBay pages related to Fraud Protection at the address provided below for information on steps you can take to ensure that your transactions are successful:

If you have already sent the item or sent payment for the item, please reply to this email and we will send you additional information about how to protect yourself.
Regards,
eBay Trust & Safety
