The bumpers clearly not lined up properly, you can see on each corner, the left is pulled in the right is popped out slightly.
Could be innocent but the kind of bloke who has his own ramps would surely just undo the 10 screws and re align it.
But I don't really see it to be anything to worry about, everything else seems to line up OK.
It was cat d 10 years ago so unlikely to still be from that!
I would go see it and have it on an alignment rig / checked on a chassis jig before selling out the thick end of £50k, but otherwise looks to be the PERFECT GT3.
One you can actually use as intended and rag around a track without fear of impacting its value or worrying about stone chips.
