Im thinking of pulling the trigger on an 08 4matic as a DD. It currently has around 80k miles. Trans and engine mounts have already been replaced under warranty.

What are typical failures of this car around 80k miles? I've heard of '07 4matic trans issues but were they really ironed out in '08? Good thing is I'll have a warranty for about a year or up to 100k but just curious if it's worth keeping beyond that point.
