Is the 1987 Buick Riviera reliable?

Routine maintenance is usually manageable, but costs can rise if you need transmission work, electrical diagnosis, or hard-to-find trim/interior parts; budgeting for age-related repairs is wise.

What are the best years to buy for a Buick Riviera?

“Best” depends on what you want—many shoppers seek later 3.8L V6-equipped Rivieras for parts support and everyday usability, while others prefer earlier or later generations for styling and features; always buy based on condition and documentation first.

What should I check before buying a 1987 Buick Riviera?

Test the transmission for smooth engagement and shifting, verify stable operating temperature with no coolant loss, confirm all power accessories work, and inspect for vacuum leaks, rust, and signs of deferred maintenance.
