You should get one as low mileage and mint as possible as there are plenty out there and the prices have plummeted accordingly. I lost £4000 on mine! Worth every penny.
There aren't really any issues that affect all Trophys, just look for a full service history, one that has had regular oil changes normally implies careful ownership and mechanical sympathy.
Don't be immediately put off by subtle modifications, quite often it means an owner really cares about his/her cars and wants the best for them. I replaced my gearknob with a Richbrook one because the OE one had worn by 10K miles and it's nasty.
Most importantly of all, take an extended test drive. It's essential if you've never driven a 172/182 before, you'll either decide it's too raw and firm for an everyday car (If you're a complete Jessie) or most likely fall in love straight away and part with cash immediately. Steve Coulter of allvehicles can help with the test drive, he's Artdealer on here.
anyways as others have said, they are obviously new'ish cars so as long as they have a fsh and no bodywork or interior damage then each one will be just as good as the next.
you can buy anyone out there without too much worry!
I'm driving to Gower tonight, not in a Trophy though, unfortunately. That's where I learnt to drive the Trophy properly, the roads are too crowded down here. Can't wait to find out how the Integra measures up against the Trophy's ground covering ability and thrills per corner, it's got it's work cut out.
