Subtle indications that a car has not been loved

[Frimley111R]

I was looking at a Megane R26, which, all polished up, looked lovely but I noticed the mats inside were knackered and on closer inspection (thank you big image facility on eBay) the wheels were quite damaged. They might be subtle pointers but the mats oddly put me off a bit. I thought that if they were that knackered (worn/curling up) that the owner probably hadn't loved the car much.

What else puts you off?
