I have a e320 cdi 2008 sport model which Mrs cossie Dunc uses as her daily transport
They are a cracking thing, loads of luxury, loads of toys and most importantly loads of torque
They also handle the miles really well, mine has just touched 245k!!! And it runs like a Swiss watch, it's been all over the world and back
I don't need to tell you how good my 75 is also
Good luck whatever you decide
