Mercedes S63 AMG vs classic 450SEL

The new S63 AMG continues that tradition, and then some. Because, for the moment, this is the quickest, most luxurious, newest S-Class you can buy, making it - supposedly - the apex predator in the fast and fabulous limousine market. And although the S63 might be slightly less discreet than one of its smaller-wheeled diesel brethren, it still doesn't loudhail its potential. Yes, there's largesse to its street presence (all the S63s we'll get in the UK are LWB), but unless you were in the know, you might miss the bi-turbo V8 badges on the wings and have no idea this monster limo could comfortably outpace all but the most modern Ferraris.
