1998 to 2000 Lesabre, Any known Chronic problems ?

Hello, I am new to this forum and I am considering replacing my failing 1985 Monte Carlo withs a Le Sabre, between '98 & '00
Does anyone know of any Chronic problems with these models that I should know about before I purchase one ? (Especially the 3.8 Liter Engine) I have read about upper & lower Intake manifold gasket failures.
I know nothing about fixing cars and would appreciate any advice you can give me.

Thank you,

Some of the models described in this recall, (link below) include the 98-00 LeSabre. Check the VIN and see if the regulator on the one you select, has been replaced, or needs replacement.

The manifold and power windows can also give problems on the same year models.
