What Should I Be Looking At That's Is Or Was A Problem With The 2007 H2

[Viet Nam Vette]

A buddy of mine is coming over today to pick me up and drag me out to look at an 2007 H2. He saw one a 2007 SUT loaded out with all the chrome gack and rear bed cover on some lot somewhere. It has Cross bars and Rear DVD Captains chairs...etc.

It has 21K miles and he said it is super clean. The Car lot is asking $39K. Now I''ll climb under the rig and look at the drive line and such for leakes as well as mud and dirt and twigs ..(Standard Off Road Hitch Hikers).... But is their anything particular to the 2007 as far as problem area's?

All Help Apreciated.....
