I am not a fan of 'classic' cars - the closest I would go is my mate's immaculate 1994 Porche 993 Carrera. But newish cars all the way for me...
So (in no particular order):
1. 2007 BMW M5
2. Audi RS4 Avant (with some haggling)
3. 2006 Maserati Quatroporte
(though I would also wait for a sport model of the GranTurismo to be released and subsequently come down in price)
4. Porsche Caymen S
5. Mercedes-Benz SLK 55 AMG (Wife pleaser)
