ok so $42,000(don't forget the sales tax at RUF register) for another 100 HP? virtually no interior upgrading. SIX figures on sub 400HP car that will draw far fewer looks on the street than a second hand Ferrari and get spanked every day of the week on the track by the average non-Z06 Corvette?

That's $428 per horse or at that rate
$4,280 for an additional 10 HP?
$6,420 for an another 15 HP and so on...

I would really like to someone who wasn't a multi millionaire that would spend this kind of dough.

Just buy a used Lotus Elise and you'll get the same low powered but quick off the line experience and keep more than you spent in your bank account.

If I were RUF I'd concentrate on making good quality yet not obscenely expensive aftermarket parts that would make sense to the average Pcar guy when considering bang for buck.
