Chris, you would be surprised at the values of Cobras coming down now, I guess due to the new GT500 coming out. I looked online at hundreds of them, then bought one. It is turning out to be a great open track carAt this point in time a 50k mile GN and 2003 Cobra are similar in purchase price if the TRs are pushing $20,000.
$20K is about the bottom for an '03-04 Cobra, like $5K was the bottom for TR's in the 90's (right after people pay them off) and then they started to go back up when people realized they were so cheap (and were still faster than the cars people replaced them with).
There are too many lesser Cobra's out there and low number of 03-04's built will keep the value high.
If there was a chance '03-04 Cobras will ever be $12-16K, I'm not seeing it. It would be cool, but I'm not seeing it happen.
