I get an email from cargurus that someone is interest in my Vette. I respond but seldom get any response back. How do I know if the interested party gets my response?

I had the same problem with my 1992 Corvette. I can't answer your question but, I do know there have been simular questions posted. BTW - That is a really nice Corvette you have.

Need to fix problem. I seem to have lots of interest but no more contact.I like the site but no help in selling car.

I believe the potential buyer is clicking the "Interested" button, just like the "Like" tab on Facebook, when in turn they are not actually wanting to purchase, just to do this! It has happened to me as well, Car Gurus should list there message as well, not just tell you that blahblah@cargurus.com is has viewed your listing!
