Honda S660

The Honda S660 currently trades at a median of £9,851 in the UK market, down 25 percent year-on-year—a sharp reversal that signals sustained depreciation pressure on this segment.

Liquidity remains critically weak, with zero sales tracked over the past 12 months and no active listings on record. This absence of transaction data makes reliable price discovery difficult and suggests buyers are largely absent from the market at present levels.

The S660 occupies the stable modern classic category with a collectibility score of 5, but desirability remains low. Without production-volume data or original pricing, the underlying appeal factors remain unclear, though the Japanese kei-car roadster's niche positioning limits mainstream collector interest.

The base projection for three years ahead sits at £5,159—a 48 percent decline from current levels. Over five years, the model is forecast to reach £4,250, representing a 57 percent total loss from today's median.

Given the combination of rapid recent depreciation, illiquid market conditions, and steep downside forecasts, sellers should act cautiously. The confidence level around these projections is low due to the absence of recent transaction data, which limits visibility into true market sentiment.
