This thread is interesting and ambiguous...and I can't make up my mind! So here's an attempt:
Daily car for same money as my daily BMW = Any old AMG saloon.
Daily car, money no object = Porsche 911 or Rolls Royce Phantom. (No, I don't have a problem with the size of my manhood, LOL)
Sunday car if comfortable = 1973 Corvette (454ci big block - what a monster)
Sunday car if super rich (sigh) = Mclaren F1.
