I love searching around for products and services that I couldn't possibly hope to afford in my lifetime. It's almost surreal to look at some of this stuff. I found a few sites that have tracked down was is likely the most expensive item in a variety of categories but there could always be something newer or they missed an item. These are expensive enough as it is so please enjoy the excess.
Car - Bugatti Veyron Supersport. - $2,600,000
Ear Buds - Harman Audio AKG K3003 - $1,300
Home - Billionaire of India. 27 stories! - $2,000,000,000 (that's right billion).
2 million dollar glorified goldfish and a million and a half for a Chow dog on steroids? My dad always said dont buy anything you hafta feed. I think those 2 qualify... Good page though. And I'll take the supercar. :-)
