All depends on the price tbh mate. No MOT generally gives you scrap value, so if its cheap enough and the shell is free from rust (get under and inspect everything and every nook and cranny!) then as Simon said above don't be too concerned about the mileage. Just the usual checks for the engine (any signs of oil leaks, blue smoke under acceleration, strange noises etc) and see how she drives. From the photos she certainly looks decent. Ive got the original brochure too! The wind deflectors if OEM Honda ones will be solid black plastic. If they are the tinted perspex ones, they'll either be Climair or Team Heko aftermarket ones, both of which are readily available on the internet.
Oh, and just spotted a mega bonus......that civic has the larger (and better) front fog lights fitted which are rare as hens teeth!
