Help needed with how your website works

I'm having the same problem, very frustrating. Was told by Cargurus to use a different email address. Adding another email is something I don't wish to do.

To CarGurus, is your website working? when I respond back to 9 different inquiries, it appears none of the people inquiring are getting my messages. very frustrating.

I'm wondering myself as others if Cargurus is really helping the private sellers, too many private sellers have similar problems and it's no help to us.
