This three-owner 1985 Buick Rivera is a fantastic example of the era when GM still focused on plush interiors and cushy suspensions. It’s a true survivor and is the last of the “Big” Rivieras before GM downsized the platform. Its 307 4BBL. Olds V8 engine motivates this luxury machine with plenty of power, the transmission shifts firm but not too hard, and everything works from the A/C, radio, and cruise control. Deep Burgundy Metallic with Burgundy interior.
