oh and for that sort of money that u have avaliable a good series 1 is in your reach and an extremly good series 2 as well.

when looking at the cars check all the panel gaps, check for damp carpets, check the wheel wells for rusty arches, check the boot behind those carpets on the side cause they can fill up with water when the sunroof seals go( mine does regulary)

engine make sure the car aint warm when u start it cause it might hide problems look for smoke, blue means oil n white is water, smoke after boosting means turbo seals are going,

just check for RUST RUST AND MORE RUST LOL!
