definately check it thoroughly, i stupidly spaffed my load on a lovely looking s2 when i was young and stupid, i didnt notice that the vin plate was missing when i looked at it, when i noticed checked the floor number and it had been perfectly cut around and some steel welded in, further checks from the vin number on the v5 showed the car up to be a stolen one that was never found from the mid 90s, luckily i returned the car to the seller as i didnt want anything to do with it
