In no particular order, this is what I would have in my 5car garage if I had the money:
-Ferrari California
-Porsche Panamera Turbo S
-MB SLS 'gullwing'
-Porsche Carrera
GT
-BMW X5M
I know some will be puzzled by some of my choices but I got 2 small boys so I had to throw in a few cars I can enjoy with my entire family. IMO the Panamera is the best 4 door sedan, it is capable of things a 4 should not be, very roomy as well. The X5M is the closest I can stomach to getting and SUV/SAV. The California is a 4-seater exotic, is a hard top convertible, most beatiful Ferrari design in many years IMO(best of all worlds). The GT is a no brainer and the SLS I can't explain, I just like the way the car looks(even the original 1955 SLS).
Also, this thread needs pictures!
