that car had new cam belt & tensioner, aux belt, P.S. belt, coolant, P.S. fluid, dist cap & rotor arm, plugs, oil & filter & fuel filter last summer, & another set of plugs (071's) just before you got it.
get yourself an efl 90 oil filter & some 15/50 mobil 1, change that & just check everything else as in a normal service. the brake fluid may be due a change.
