Thinking of buying an 06 325xi wagon auto 100k mi

Hi there,



I'm thinking of buying an 06 auto 325xi wagon and was hoping to get advice on what to check for. It seems the engine cooling system is a typical thing to watch out for, but what exactly do i need to look at? also i read about the boots, i guess thats an easy one to check. Valve cover leaks should be easy to spot right?

How about rust spots? any particular things to look for beyond the usual wheel well and underbody stuff?

Thanks in advance!
