Lol QwikSHO! Poor you! It almost seems like the SHO is not for you...
But I understand your points. I would say that some of the points ciuld be addressed indeed by FMC, others are only a matter of taste and other are arguable. The 6MT would be fun, but probably slower or at least less consistent (at the drag, manual cars suck). The twin turbos don't have the same lag. For about 5K$, as of today, you can bring your car from 365 hp to more than 500 hp... Maybe a single turbo is easier, but at least we do have turbos! N/A cars are the ones difficult to mod and require expensive bolt-ons to get more power...
Finally, at one point, for some of your complaints, I guess it goes with the price... You can get A6 3.0T or BMW 535i, they will offer better interior quality... But then you need to pay the extra 20K$...
Cheers!
