I've gotta say, that looks like a pretty inaccurate list. Yes, there was a reason they only included certain cars, but there are many other cars not on our shores that have an extra digit or two at the end of their price tag.
That list is not very accurate. First of all the Porsche GT2 is Porsche's second most expensive Porsche. The Carrera GT is the most expensive at about $500,000. Also missing on the list is the Enzo Ferrari which is around $1,000,000 and you have to be "invited" to purchase it, they just won't sell it to anyone.
I was going to say the same about the MB selection... the CL600 isn't even close to the highest priced Merc now, behind the SL65 at $17xk and the McLaren at $4xxk...
Not the mention the F1 McLaren isn't even mentioned
