Things to watch on the Buick:
- window regulators (cable drive that likes to come off its pulleys and bind up)
- rear air shocks prone to leaking with age, listen for the compressor (behind passenger quarter panel) coming on excessively
- watch for coolant in oil, the lower intake manifold gaskets were prone to failure. Not very difficult to replace
- plastic coolant elbows into/out of alternator bracket, if O-rings get old they will pop out under hard acceleration, watch for weeping
- transmission fluid serviced appropriately, some have had issues in the low-100k range but my buddy's wifes 2002 LeSabre has 230k on the original transmission and it is just starting to have downshifting problems
- block heater (if equipped) prone to popping out due to overtorquing, the brass retaining tabs break off. Cheap/easy fix. Mine went and I shut off the engine as soon as my heat quit and I saw the steam.
