Honda S660

The Honda S660 is trading at a median of $13,200 in the US market, down 25 percent year-over-year—a sharp depreciation signal that warrants caution for current owners and skeptical buyers alike.

The market for the S660 shows extremely limited transaction data, with no recorded sales tracked over the past 12 months and zero active listings observed. This illiquidity makes pricing volatile and difficult to establish with confidence; any valuation should be treated as preliminary given the sparse trading activity.

Classified as a stable modern classic with low current desirability, the S660 occupies an awkward middle ground—too recent to command vintage appeal, yet distinctive enough to avoid mainstream used-car demand. The car's niche positioning as a lightweight kei-car roadster limits its collector base significantly in the US market.

Base projections paint a concerning three-year outlook, with median value expected to decline to $6,913, representing a cumulative 47.6 percent drop from current levels. The five-year forecast extends this trajectory further, projecting $5,694 by year five—a 56.9 percent erosion from today's price.

The combination of depreciation momentum, near-zero transaction flow, and weak desirability scores places the S660 in precarious territory. Sellers should consider action sooner rather than later, while prospective buyers would be wise to await either stabilization signals or a more compelling entry point.
