Buffett probably doesn't drive much in Omaha. Maybe the car only has 25,000 miles on it. Why buy a new one? Who is he trying to impress?
As for the Porsche. I tried your favorite web site (995ad.com) but only found 1 1999 Porsche but no price listed. I then went to AutoTrader and located more than 150 1999 Porsche Carreras under $30,000 with the least expensive being $22,950. There were some plain 911's for even lower prices but I am giving you the pricey model.
and i wont say what i have sure alot better than both of those.
I doubt Buffett or Gates are any more impressed than I am..... which is to say, not at all.
