If you're at 60k you're in for a new belt in the next couple years. Honda belts are 90k.
Do what RDN said and get a pre-purchase diagnostic, along with an estimate to repair all the issues they find. It might seem expensive ($80-$130) but I've bought two Preludes and both times, the seller took the estimated repair price off the selling price! You can't expect that to happen every time, but both times I saved hundreds of dollars.
Preludes are very reliable, just try and make sure all your maintenance is preventive.
