You guys do notice this right?
"The Enzo Ferrari is the greatest contemporary car that money can buy ... An expert panel of motor pundits conducted an in-depth analysis of all the cars currently available on the new car market retailing at over £50,000."
That will be the main reason that McLaren F1 wasn't on the list, as it's not a new car from recent time. However i don't really agree with the list, I don't think the Bentley and SLR deserves to be there. As for the top spot, there is no reason to argue against it as heritage is included, but if heritage is not included, the Zonda will get my vote.
However, the McLaren F1 will always remain the number 1 on my list
