Looks good! It seems to be totally original - even the faucet, which has usually been replaced. The range shouldn't be much of a problem if it's not working properly, as it's basically a regular GE 24" range with the surface units in the SS countertop instead of the usual porcelain enamel top. The dishwasher and W-D units would likely be another story.
I do know that the custom fabrication charge to have a SS top made in that size, with sink and openings for the surface units, would well exceed the asking price for this unit.
