I always try and park in the same place, this place is always in a corner, next to a wall(s) (if possable) as these are usually slighty larger spaces.

I do notice that other people (some for the same office as me) have started to try and nick 'my' parking space (yes i'm talking to you with the blue Audi TT).

I like to look after my car (ok so i'm totally anal about my car and how clean and tidy it is) so i tent not to park next to scabby cars at any time.
