My bro and mate both have '97 VTi-R's (both owned from 108,000-160,000km), I have a '99 (72,000-117,000km) so feel free to PM me random questions.

Some things to check of the top of my head:

-a few annoying rattles can be normal

-original radiator top tank cracks around 110,000km, and is a very dark greenish colour, the replacement is black. Not expensive.

-check for shakey sunroof operation, needs greasing but should be ok

-door lock actuators can fail, but an inexpensive fix

Seriously if it looks the goods after a close inspection and good drive, has a good service history then chances are it'll be fine. All three of us have had virtually no issues to speak of, just general wear and tear.
