The repairs the current owner performed sound like he's addressed several common issues these cars eventually have. Fuel pump, fuel distributor, ignition distributor, A/C, rear window mechanism, timing chain, injectors, injector holders, idle air distribution hoses, cam oiling lines (inside valve cover), valve stem seals, vacuum lines are all common items to repair or replace over time. Valve stem guides need to be checked at around 150,000 for play.
Hope this helps.
