Mercedes-Benz S-Class

Without a doubt the benchmark big luxury saloon, the one Audi, BMW, Lexus, Cadillac and even Jaguar and Maserati must define themselves by and be measured against.

This car defines the sector and is the one all others must topple. The latest A8 and 7-Series are closer than they have been in the past, but while both are excellent cars in their own right, neither is quite as special as the S-Class.
