I got that email too...
Hmm, it's the 15th and they say they need confirmation by the 20th or the order will not be processed.
I wonder if this is a step towards making sure people can't sell their car before taking it. It seems that 5 days isn't very long - if I was out of town and lost my spot due to this, I'd be POed! I often don't check my email for days on end.
I Just called... YOU MUST HAVE YOUR CERTIFICATE NUMBER OR YOUR CURRENT VIN NUMBER OR THEY CAN"T HELP YOU!!!!
The certificate number IS NOT in the email!
If you DON'T have either of these pieces of information, they say you should RESPOND to the email saying that you want the car, and they will send you back a confirmation email.
It seems this is an attempt to get each owner to commit to buying the car. I wonder how many profit-minded folks will get weeded out at this phase????
EDIT, they will reply to your email with a confirmation EMAIl, not a confirmation NUMBER.. sorry
