This ones a no-brainer. Get your mechanic to fully check it out. Some usual wear and tear items are:

-suspension bushes (esp. trailing arm bushes)
-radiator top tank
-engine mounts
-clutch and gearbox (if the box stiff or u detect slippage, it'll be the ready for an overhaul which is never cheap)

A Honda with less than 100,000kms is still a baby in my eyes. Of course revheads could have made it age very quickly. After all, an ITR is a serious sports car, not an overpriced shopping cart. Your radar should be working overtime when u are buying one of these. It's dodge city when u are looking for a quality 'teg, maybe one out of every 7 is a well-cared for example.
