The 1994 Buick Riviera is a personal luxury coupe designed for comfortable long-distance cruising with a strong V6 and a smooth, quiet ride. It’s part of the eighth-generation Riviera (1995 redesign came later), and it represents the final phase of the previous, traditional front-wheel-drive Riviera formula. This model year is ideal for drivers who want a roomy two-door with classic Buick comfort, soft road manners, and an upscale feel without the pricing of European luxury coupes. In the market, it sits as a plush, mature alternative to sportier coupes, prioritizing refinement over sharp handling.
