Alan Mulally has done a good job with Ford and not just with the new Mustang. Still it's a luxury car versus a non luxury car. You can always find a car that is cheaper and faster but there are bound to be tradeoffs. In the end it's about what makes you happy when you are behind the wheel.
I like the Boss 302 but I need a sedan so the M3 is the most likely car for me. I'd prefer AWD but as of now the best option is a M3 sedan with snows (and chains if need be).
That is unless the Panamera Turbo drops like a brick in the next couple of years.
