Mercedes-Benz SL (R107)

The Mercedes-Benz SL R107 has fallen to a median of £14,308 in the UK market, marking a sharp 24.6% decline over the past year. With a clear SELL signal in place, the trend is decisively downward and shows no signs of stabilization in the near term.

Recent transaction activity reflects the broader depreciation pressure—25 sales tracked over the past 12 months suggest consistent but modest liquidity, though momentum remains negative. The wider dataset of 55 total sales indicates this segment moves regularly enough that buyers and sellers can transact without extreme difficulty.

Production volume of 237,287 units positions the R107 as a high-volume classic, which fundamentally limits collectibility appeal. Classified as a stable modern classic with modest demand (score 3), the model lacks the exclusivity or specification variations that typically anchor values in the mid-market.

Average mileage on transacted examples sits at just under 31,000 miles, reflecting the typical profile of well-preserved garage cars that spend limited time in active use. This low mileage is consistent with the model's trajectory as a secondary investment piece rather than a drive-daily classic.

The outlook darkens considerably over the medium term. Base projections point to £7,305 in three years—a 48.9% drop from current levels—and £5,975 within five years, representing a 58.2% cumulative decline. These forecasts assume continued supply pressure from aging stock with limited collector enthusiasm to support prices.

With only one active listing currently tracked, supply-side urgency is not acute, but the fundamentals suggest this is a buyer's market. Owners holding R107s should recognize that holding for appreciation is no longer viable; the window for exit at current or better terms is narrowing.
