We have 17" wheels and winter tyres on the E220 estate at the moment - a much more comfortable ride than the 19" wheels wheels with summer tyres.
I'm going to get a set off all-season tyres for the 17" wheels and leave them on all year round.
On my E500 A207, currently I have 18" wheels and winter tyres - again noticeably more comfortable ride compared to the 19" wheels with summer tyres.
