look for rot on rear chassis rails( where the suspension bolts up) , rot on front chassis rails where they meet the bulkhead, rot on inner wings up by bulkhead, rot on rear arches, rot in boot floor, look for any evidence of severe damage that has been poorly repaired, look at the chassis numbers in the floor make sure they are raised in the car and not stamped down!!!
look at the tyres to make sure the wear is even across them as this is a surefire sign of chassis misalignment

the 200 is in big numbers, cast on the side of the block(just like the 205)
