For £7.5k I'd look for a nice Rev Up.
General consensus is that mileage doesn't mean much, it's all about condition, so make sure you check that thoroughly above all else. Link us to any adverts you are considering and we'll do our best to help.
Definitely go for the coupe. Less to go wrong and looks much better.
AFAIK, and I'm sure someone will correct me if I'm wrong, but you can use either - they both fit.
It could just be a late pre-facelift.
The same way I have an 07, which most people assume would be an HR, but it's just a late RevUp DE.
I wanted black or white, cos I prefer most cars in black / white, but on a Z it's meh tbh.
Silver looks great, so does the bright orange, and San Marino Blue is amazing.
Ah, didn't look that closely, just saw the HR bonnet.
Probably still worth enquiring further, and you can check the corrosion for yourself - hard to say what it really is and they might've got it sorted.
