The V6 engine in the Buick is solid except the intake gaskets fail. Plan on $1,000 or so to fix that. Have a mechanic check for rust underneath especially the brake lines. New lines done by a competent mechanic are not expensive vs the alternative. If there is not much rust you could have a great car. If you buy a used car from someone else you can plan on spending $$ on the surprises the seller did not disclose. Always have a mechanic check the car before you buy.
