You need to understand that IF there wasn't money to be made, then Naples Motorsports wouldn't be carrying the line its that simple! Ron Ward has been in the automotive business for many years as have Naples Motorsports too. And they have sold a few cars in the last couple of months so they must be doing something right.
You can ask how many buyers are willing to pay $x.xx amount on a Saleen just like you can Roush, lingenfelter, renntech etc. There is a market for such vehicles because if there wasn't, non of them would be around. BUT, the biggest difference is that Saleen actually crash tests there vehicles to meet safety standards and doesn't just slap bumper covers on it and calls it a day.
Have you ever driving a Saleen Mustang? My guess is no. So my suggestion is for you to go for a ride in one and then tell me if it is or isn't worth it because I can tell you that you will get a lot more attention with that $100k Saleen then you will a $100k other high performance vehicle and at the same time be supporting a company that manufactured that vehicle in the USA.
