88URABUS

Just purchased a 1988 GL 10 Wagon with 56,781 original miles from a coworker for $900.00. This is a southern vehicle NO RUST!!! Has new tires and struts everything else original. Everything works except for AC. This car starts right up and handles great! Where should I start in getting the ac fixed and should I go ahead and get the timing belt changed? I will be putting on new plugs, wires and fuel filter this weekend. Any suggestions on servicing the tranmission at this point? By the way no leaks anywhere on the engine or tranny. It is a FWD AUTOMATIC with sun roof, pwr everything. Does anyone reccommend using synthetic oil? Any suggestions would be appreciated
