I agree with the post...no major problems with 95 SC400 at 223K miles about 90% of maintenance items mentioned in the post above.
The maintenance is not that expensive if you take it to a good shop and not the dealer, At 120K I replaced timing belt, water pump, accessory belt, distributor/cap, plugs, and wires for about $1000 including OEM parts..ordered from parts.com..way cheaper than local dealer.
