How do you know that these cars wouldn't work as everyday vehicles for the people that are posting them, Joey?
My current daily driver is a small-by-modern-standards two-door RWD sedan, with backseats
just big enough for two adults and a modest trunk capacity. I drive it year-round on ordinary all-seasons despite the snow and RWD, I very, very rarely carry more than one passenger, and I almost never use even 20% of my trunk capacity. Pretty much all of my normal driving time is commuting between work, home, or friends' houses, with the rest spent on enjoying backroads. Almost always by myself.
For my current daily needs, a "practical" vehicle like a big-ish sedan or wagon would be a waste. On the other hand, a 911 would fit perfectly. In fact, the AWD of the Turbo I posted would make it a
better winter driver than my current car, and the performance would make it very enjoyable on those backroads.
The same goes for the Z4M Coupe, and most of the cars posted here.
Don't bother asking me what I'd get if I were to start a family, because you should know the answer would be an M5.
