Although the F40 is in a league of its own as far as Ferrari's are concerned, The Aston would be an investment for the future. You have to consider image heare too, some one who buys as F40 may be seen to be hitting a mid life crisis in a very big way. Whereas an aston would be some one who is ageing gracefuly, and prefers the finer things in life, but who still likes to let his hair down every so often. It would have to be the DB9 for me.
