check the body for signs of crashes, then make sure they got that taken care of, i bought my mr2 with a dent inside the frontcomparment/hood, i knew it was in a accident, but it looked fine, turns out it has 450$ cost of frame damage that i still need to get repaired, the car looked fine so i didnt care too much, but if i was involved in a accident, the poorly placed bumper would've done more damage to my side than the other vehicle. thats something you can look for in any car i guess, now my touge monster is rusting up without a bumper.
