trick25 - welcome to the site - lots and lots of good info and people here - as far as the NOS, 100hp or less should not hurt the engine as long as it's a proper kit with fuel enrichment. I would keep looking for a MM - if you look here you may find one or look at the dealerships, you may find what you want - with the discounts from Ford and the dealers you may find buying a new one a better deal since you can get lower financing rates from a bank on a new car. Do your homework and find which option is best for you, and buy one - I've had 28 cars from a lowly 240D Mercedes with a 4-speed manual and 270,000 miles to a 2001 Audi S4 Avant 6-speed to a 97 C5 Corvette with about 425 rwhp, and by far the Marauder is my favorite car I've ever owned.
