viewing a 135i coupe what to look out for?

[Liamst]

Hi so basically as the title suggests i will be viewing a 135i this evening provided the blackwall tunnel does not try and stop me and was just wondering if anyone had any advice for things to look out for?

It has full bmw history and is a 2008 so an N54, I know of HPFP issues but i believe these are now covered by extended warranty by bmw?
Anything else or input appreciated.

Thanks in advance
