456 GT vs 456MGT vs 550 vs 575

What would be really interesting is to hear from owners of these models how they feel about these 4 cars. Not from the point of repairs, we all know about the wind noise and the dash and the seat and the windows on the 456, and the motormounts, and we know the 575 is finished so much better, but the 456 is more subtle in style...Ferraris are meant to be driven, and so the question is: How does it make you feel when you're in that 456M or that 550? Which one is better? The 456GT because it feels like a classic, almost like a 365C4? Or the M, elegant smooth power? Or the 575 power flash? Be great to have your comments!
