And, oh yes, I was a maniac before retirement, owning six 911 Turbos, three 911s, three NSXs, a ZR-1 Vette, Viper RT/10, Lotus Espirit S4S and a Callaway TT Vette. And those were just my sports cars. My "family cars" included two M5s, two E-55 AMGs, a C-63 AMG, a C-32 AMG, an M6, a MB 2.3-16 Cosworth, etc.
The point of all this is that I have some experience to intelligently discuss the matter.
