Simple enough to see that the speedometer and tachometer are working reliably and the trip odometer can still be reset. A bad instrument may not be a deal killer, but it should figure in the price.
The biggest nuisance of the 2002 was probably the bubbly/fuzzy/flaking black paint on the engine, gearbox, and rear drive. Some of these have been addressed in various ways. And it may not be troubling to you, but it is a 2002 issue to look for.
Charging and electrical issues can require some attention, so checking voltages key on/at idle/ and at RPM can give you an idea if the charging system is healthy.
As posted, the only deal killer would be that you ride it and she doesn't speak to you. Otherwise, anything that comes up is do-able!
