Are you just typing to see the letters? Why do you have a GT3 RS when you could have just thrown slicks on a Cayman with the 2.7L? Fast can be fun, both in turns and the straights. I loved my Miata, especially at the track, but I also enjoyed my M Coupe at the track plenty. I lapped a Gallardo and also got beat up by plenty of Spec Miatas.
But back to the F30 vs a Lexus, since one comes with a stick, it's automatically more on my radar than the one that doesn't. I realize I'm a dying breed, but it still influences the cars I shop for.
