By 1997 most of the gremlins in the early ones (disintegrating gearboxes, misaligned timing belt failures) were ironed out.
The first thing I would do is a full service including all the oils i.e. gearbox oil transfer box oil both diffs and the swivel housings, set the tappets etc, you never know how long since it was last done and a bit of fresh oil goes a long way towards preventing future problems. If you don't know for sure that the timing belt has been changed in the last 4-5 years get that done too as the rubber belt will perish by about 6 years go ping and you'll need some bits for the engine - it is a service item but one which often gets overlooked. If it had the belt alignment problem it will most likely have been fixed under warranty but depending on when it was built it might be OK anyway, 1997 was when the "kits" started being factory fitted.
If you want something else to do, a bit of grease in the wheel bearings never hurts as preventative maintenance and isn't hard to do, a seized wheel bearing at speed can be "interesting"....
Other than that just take it as it comes and enjoy
