If there was moisture in the crankcase, and it sat, there could be corrosion on bearing surfaces of the crank and such, which will result in scoring of bearings. That you don't know. Considering the Catera was only around from 97-2001, there is not much value in them, regardless of condition. You may be able to get an idea by building a private party resale value on a site like Kelly Blue Book.
