Buick Riviera (1st gen)

The first-generation Buick Riviera sits at a median of AUD $117,500 in the Australian market, but carries a clear depreciation signal with a 25% year-on-year decline and a high-confidence outlook suggesting deeper losses ahead.

The model is classified as a collectible with a score of 6, though desirability remains low and liquidity is severely constrained—there are no active listings tracked and zero sales recorded over the past 12 months. This absence of transaction data makes price discovery difficult and suggests Australian buyers have limited interest in this American classic.

The three-year projection indicates a median fall to AUD $61,533, representing a 47.6% decline from current levels. Over five years, the base case points toward AUD $50,689, or a 56.9% cumulative loss. These forecasts reflect persistent weakness in demand rather than cyclical softness.

With no mileage data available from recent sales, condition assessment and comparative valuation remain opaque. The illiquid market status means buyers and sellers face significant friction; those holding examples should consider that patience has not rewarded recent owners.

The combination of zero sales activity, low contemporary desirability, and sustained price pressure suggests the 1st-gen Riviera faces headwinds in this market. Sellers should not expect conditions to stabilize in the near term based on current trajectories.
