I can see a little lust for that motor. Ford makes some great cheap powerful cars, with the emphasis on cheap and powerful. When I was 17, sure, I wanted a 5.0 really bad. Or a Saleen, or whatever. But, have you been in even a nicer Mustang? They are shit. Plastic everywhere. And they fall apart terribly. It's like the Wrangler: dumb kids under 25 want them and don't force the market to make them more practical, long-lasting or reliable.
If I had $35k to spend and wanted to buy a car like that, I would buy a used C5 or change my budget and buy a C6. GM is lights years ahead in true muscle car technology. All Ford can do is make a profitable, but crappy, pony car, and many variations thereon.
Sure, the Cobra R was great in the numbers, but would you really want a car without a stereo, AC, power windows or just about any sound deadening? It was a purpose-built track car.
