Purchase advice Volvo C30 2.0 Built 2007

Hello all, I looked at a Volvo 30 2.0 year 2007 yesterday, according to forum this is probably a 2008’er model, because in front of the can holder of the central tunnel comes down like a waterfall and the disguise of it in such a metal is printed with so frills. I don’t really know about the car but I like it*fg* This is a 2.0D, summum with 75,000 km, xenon, seat heating, parking aid, cruiser, Navi, leather, checkbook and from the Volvo dealer for 12,000 euros. What do I have to take into account when buying it? Did I see on the site yesterday that the headlight has a “small” jump How long does about with “normal” driving of the engine, am unfortunately smart damaged;-) Can one mount an AHK on this car at no high cost?
