The first-generation Riviera, designed by Bill Mitchell, introduced a knife-edge silhouette that rivaled the Ford Thunderbird. It represented GM's entry into the personal-luxury coupe market.
2nd Generation • 1966-1970
This generation featured hidden headlamps and a more luxurious interior. Although it shared the E-body platform with Cadillac and Oldsmobile, the Riviera remained true to its rear-wheel-drive roots.
3rd Generation • 1971-1973
The peak boattail era of the Riviera showcases its distinctive styling combined with powerful performance options, including the GS Gran Sport, making it a highly collectible vehicle today.

With the introduction of federalized bumpers, the fourth generation continued to offer the 455 cu in V8, balancing classic styling with modern safety regulations.
5th Generation • 1977-1978
This generation marks the downsizing era with a Colonnade design, transitioning the Riviera into a more compact and efficient personal-luxury coupe.
6th Generation • 1979-1985
The E-body Riviera was noticeably smaller but still managed to retain rear-wheel drive, continuing to appeal to luxury-minded consumers.
7th Generation • 1986-1993
This generation made a controversial shift to front-wheel drive with a transverse-mounted engine, representing a new direction for the Riviera.
8th Generation • 1995-1999
The final Riviera generation featured the Northstar V8 and supercharged 3.8L V6, embodying modern luxury while honoring its storied past.
Known issues by generation
Each generation of the Buick Riviera has its unique set of known issues. The 455 cu in V8 models from 1970-1976 often face common problems with carburetors, ignition points, and cooling systems. The Northstar V8 in the 1995-1999 models is notorious for head gasket failures, which can be costly to repair. Transmission shift quality can degrade over time across various generations, with specific concerns for the TH400 and 4L60E. Additionally, the distinctive boattail rear windows of the 1971-1973 models may suffer seal leaks, and the specialty glass can be hard to replace. For GS Gran Sport models, verifying the authenticity of Stage 1 packages is crucial to maintain their collector value.
Donation value by condition + generation
The value of a Buick Riviera varies significantly depending on its generation and condition. Driver-quality models from the 1986-1993 and 1995-1999 generations may fetch between $5,000 and $12,000. In contrast, the earlier 1st and 2nd generations can command $15,000 to $30,000, with the coveted 1971-1973 boattail models reaching upwards of $30,000 to $80,000 or more, especially for well-documented GS Gran Sport and Stage 1 examples. Documentation such as the original build sheet, cowl tag, and Protect-O-Plate is critical for collectors, especially given the premium placed on original paint and matching numbers.
