How did you get an S class 500 when the 2014 S class only comes in a 550 and a 63 AMG?
My UK s500 is a twin turbo 4.7 V8 long wheelbase. You can even get a S400 hybrid with 2.2 litre diesel plus electric motor in the UK.
My car was made in 13 but registered in Jan 14 so probably the last pre model one available and I got a big discount.
I also have a diesel S320 which I've had since 2008 and is now used as a pool company car.
In the UK the current S500 is a 3.5l v6 petrol plus electric motor hybrid. 155 mph, 100 mpg. 5 seconds 0-60. Didn't fancy a hybrid though.
