Computer on 1990 Cadillac Seville

I've been told this model vehicle has had problems with the computer system and I should probably sell it, or it could turn into a money pit. Any thoughts on this ?

dont know what they are talking about. the computer, if it needs one, is inexpensive and not a common failure. take it somewhere else for a check. sounds like the guy just does not want to help you.

Thanks for the info. That was very helpful.
