"New" '88 88

I am considering the purchase of a 1988 Olds 88. I have found one that is in showroom condition, not a sign of rust, still has the factory floor mats even. with 121k, the only thing I noticed was a stone crack in a headlight lens, and the speedometer is a little shaky. Does anyone know if the lens is still available from GM, and is the speedo run by cable or electronics?
Are there any gotchas I should know about?
I had an '89 98 that I sold at 318k, so I am hoping this one is as reliable.
Thanks

Well, at least I know which forum is totally useless.
