A) no, while opinion regardless, the Mustang interior and options smokes the GC... hands down, if you are arguing this go get your head checked. Camaro and Challenger, meh... they are at least built better.
B) Mustang 300 hp V6 starts at $22k? 410 hp V8 ~$30kish... obviously more for accesories and whatnot, but however you slice it the Mustang would be the better deal if you want the HP. Not to mention the HUGE Mustang aftermarket.
C) I like Hyundai, but try selling your car without losing your ass... Hyundai isn't known for sport(ish) cars.
D) Again, get your head examined if you think the 370Z interior is on par with the GC... The materials are better than the GC (Suede trim, various color leathers that are designed for the car unlike GC brown leather), and I've heard alot less complaints about stuff rattling loose and whatnot. Not having backseat could be a drawback, but could be a positive... if you're gonna use that argument, the functionality of a WRX hatch or speed3 wins over the GC anyways.
E) Of course they're different cars, that doesn't mean they aren't competitors.
I'm gonna have to take a closer look at the BRZ/FRS now... I initially ruled them out for being a 1st year platform.
Yeah thats what I figured, you obviously have a tremendous bias against Hyundai for some reason. You actually believe that the Mustang's interior is better than the GCs and that Challengers and Camaros are built better than the GC. There is no point in discussing this with someone whose mentality is still stuck in the 90s.
I compared two coupes (370/GC) and your bringing in hatchbacks into the discussion why not throw in the JEEP STR8 in there as well....wow.
