Change the oil, change the control arm bushings, and rack bushing, give it a good tune up (air filter, cap, rotots, check timing belts, clean injectors, change spark plugs and wires, replace negative battery ground cable, etc) Replace the burned out dash needles maybe at Lextech lighting or do it yourself, blackening AC climate control LCD screen will need replacement too, Allign those rear wheels.. That's about everything I could think of off the top of my head with a 1992 SC400 with 200K...
Is it burning oil yet?
