Honda S660

The Honda S660 sits at a median of $13,200 in the US market, down 25 percent year-over-year. The downward trajectory carries a sell signal, though confidence in this reading is low given the lack of transaction data to anchor the trend.

The classification as a stable modern classic reflects the car's design heritage and niche appeal, yet desirability in the US market registers as low. Production volumes remain unavailable, but the S660's limited availability outside Japan and its compact roadster positioning define its collector base narrowly.

Transaction liquidity is minimal—zero sales were tracked over the past 12 months—making current price discovery unreliable. With no active listings and virtually no secondary-market activity, buyers and sellers in this segment face significant friction in establishing fair value.

The three-year projection suggests a further decline to $6,913, a 47.6 percent drop from current levels. The five-year base case points to $5,694, representing a cumulative 56.9 percent loss. These steep forecasts reflect weak US demand, the car's niche positioning, and the broader depreciation curve for modern-era Japanese imports with limited local following.

Without transaction evidence and with zero active inventory, this market segment lacks the depth to support collector investment. Owners or prospective buyers should treat pricing forecasts with particular caution and consider waiting for clearer signal before committing capital.
