Simple guys. The Saleen folks are there to make money, and there's a lot of cash to be had in the low-end ricer bracket. $25k and you get yourself a fast-n-furious'd Focus. For every person with the money to buy a proper high-performance automobile, or the time to work on his ride, there are 10 with neither money, time, nor really the interest. They just want to get laid.
You folks will speak ill of Nitrous Oxide, but if all you want is to go a little faster in the 1/4 mile, and you don't have the cash to spend on real improvements, Lazs' "baby bottle" is the way to go. It's cheap, and it gives that performance boost when needed. Plus many of the kids think it's cool.
And styling like that reminds everyone that the owner is an idiot. On the road, I appreciate warnings like that.
I did this last ricer thread. If you want to buy some sort of modded Focus, the only way to go is the $60k ATI Terminator Focus:

Oh, and heh, I saw a stock Evo-8 on the road the other day. Now that is an _ugly_ car.
