I can agree to a point that the Mustang would be better with a more advanced chassis and definetly a better powertrain, but I believe a big part of the car's charm is how easily it can be modified and the results you can get and while the culture is rife with cowl hoods and Saleen wings, each car is an expression of its owner and thats what makes it so popular.
So its my opinion that as the Mustang nears automotive perfection , its reaching a point of diminishing returns on the satisfaction scale (even though I keep screaming for a better engine
)
Anywhosit, it would suit me just fine if the next gen Mustang had a solid axle and a two valve motor. but in that context I would like to see a good T/A set-up in the raer and a 2 valve 4.6 making 300 hp and that would probably do for another 20 years or so
