I hate this. yes you can buy find a 03/04 cobra/mach with 50k or 29k in op case and its a $20,000+ cobra and $17k+ for a mach. i am sure somebody will say i bought a 20k miles cobra for $17k whatever dude its probably ragged. point being a cobra for $25k you can spend a few grand more and buy a used gt500 with more miles etc etc or a newer 5.0 etc etc its always something man.
i understand they made a ton of them but nobody will give anywhere near kbb or nada for that matter so please enlighten me why book values matter then since you seem like you know all????
There is a much bigger jump from a gt to cobra than cobra to gt500. You're comparing apples to oranges. Most people who are spending 13k are on a budget so to hear for a few more grand they can get a mach or cobra they will most likely try.
Someone who has 25k to spend on a cobra can probably afford a GT500 if they wanted to.
It doesnt matter really, all it takes is the right person to come buy this car.
