Besides the normal items on cars/trucks, are there any specific inherent probs I should look out for when inspecting a 2000 ML320 to buy?

I've driven a few Mls in the past, but fell in love with the way this one drove with 60K miles on it. It's a non-MB dealer so the only warranty is the 1 month 1K miles.

Any and all comments highly appreciated, Thanks!
