ml450

Have a set of spare 19" rims and need/want to buy winter tyres. Car is currently on 265/40 x 21" so should I go 255/50 x19 255/55 x19 If can only get hold of 4 of latter at 55% profile will it cause any issues to drivetrain/transfer box.

Hi all, So the ml450 I'm really keen on, and in the market for one but there is only three for sale from what I can see. They seem to hold a lot more money compared with the 350cdi but I found the 3.0l diesel ML slightly under powered although in my E350 cdi coupe the 3.0l is fine and pulls well.

Looking to buy a ml450 but just thought id ask if anyone has anything against the diesel v8?
