I am going to start an aero parts business and for the first part, I want to build something for the most popular vehicle in the country (And the one most in need of some help from Aero! :-)

I dont propose to be a genius, just took the standard aero template and am going to build one for now, test it, see what it does.

My questions are these:
1) Is there some grievous design flaw with the "top and tip" I want to build?
2) Can it be better?
3) What might people gain in mpg for a guess?
4) What might people pay for one all done, pretty and ready?

Thanks!
Tom
