OT-Bought a 1983 944 non-turbo, FYI $1600, clean Title, running car-had head repaired Options

[A&PGirl]

I'm going to look at a 1983 Porsche 944 non-turbo, 5 speed at noon. It has 95,XXX miles. Clear Title. Runs and drives. Could be fuses, intermittent relays on the radiation fans or thermostat not getting up to temp.

The work done:

Timing Belt, Pulley, throw-out bearing, distributor, alternator, clutch slave cylinder, radiator, speed sensor and starter, TPS and new vacuum hoses, new CV joints both, new head gasket, head machining done a by Factory trained mechanic, new driver's window, new plugs, and new rear axle.

Needs:

Battery

Near future:
Full belt, pulley(rollers), waterpump, thermostat, seals, front & rear hood shocks, front spoiler, front bumper, drivers door panel, plastic piece around the steering shaft, plug for windshield.

My Question is what do I need to look for and where do I need to look? What should I go ahead and replace immediately if I purchase it?
