Just had a quick look at the red Nismo, here's what I think:
1. Car has been resprayed, door handles are body colour and blend very well, which tells me they were sprayed at the same time with the doors / other panels. From what I remember Nismos don't come in red, but I might be wrong.
2. DRLs are missing, sounds like a front crash, didn't want to replace these when rebuilding the car as they're expensive
3. Wheels have also been powdercoated, not the original finish.
4. Front bumper doesn't align properly with the bonnet, could be an aftermarket / EuroCarParts bonnet or the it wasn't properly adjusted.
HPI check seems to pass, but could be an unrecorded accident. Needs a proper look and way better price.
Good luck with the hunting.
