Porsche Boxster (987)

The Porsche Boxster 987 median has fallen sharply to £12,250 in the UK market, down 27.5 percent over the past 12 months on a small sample of five tracked sales. This decline signals a clear depreciation trend that shows no sign of stabilizing, with the SELL signal firmly in place given the persistent downward pressure.

Liquidity remains thin, with only 23 total sales tracked across our full dataset and just one active listing currently visible. The modest transaction volume means buyers face limited choice while sellers may struggle to move stock quickly, particularly at asking prices that haven't adjusted downward as rapidly as market values.

The 987 generation carries a Collectible classification with a score of 5, though desirability remains low—a meaningful disconnect that reflects the model's current position as a maturing modern classic caught between affordable used-car status and genuine collector appeal. Average mileage on transacted examples sits at 22,181 miles, suggesting most survivors remain in relatively fresh condition despite their age.

Base projections point to sustained weakness, with median values forecast to fall 51.3 percent over three years and 60.7 percent over five years, reaching £5,964 and £4,814 respectively. This steep trajectory reflects the combination of thin demand, model proliferation across generations, and the market's shift away from air-cooled and early water-cooled Porsche sports cars as safe collectibles.

Owners holding stock should consider selling into the current market rather than waiting for a recovery. The confidence level on this outlook is high, making this an opportune window for liquidation before values compress further toward used-car fundamentals.
