Mercedes-AMG SL43 (R232)

The Mercedes-AMG SL43 R232 has fallen to a median of £63,209 in the UK market, down 24.9 percent over the past twelve months—a sharp depreciation that signals ongoing weakness in this segment. With only two recorded transactions in that period, confidence in pricing is medium, and the downward momentum shows no sign of stabilizing.

Liquidity remains severely constrained, with zero active listings currently tracked and just a pair of sales across the entire year. This illiquidity makes it difficult for sellers to find buyers and for the market to establish reliable floor prices; when inventory is this sparse, individual sales can move the median significantly.

The SL43 falls into the depreciating modern category, classified as having modest demand with a collectibility score of 3. Low desirability and modest production figures mean this model lacks the appeal that underpins values in the convertible sports-car market. New-generation SL variants have been slower to gain collector traction than their predecessors, and this entry-level AMG variant is particularly vulnerable.

Recent examples have typically shown very low mileage—averaging just 679 miles—suggesting these cars have spent more time on dealer forecourts or in private hands than on roads, which raises questions about buyer enthusiasm even when new.

The three-year projection points to a further 14.3 percent decline, reaching around £54,170, with a longer five-year outlook declining to £52,556, or 16.9 percent below current levels. The combination of modern depreciation curves, weak collectible appeal, and sustained illiquidity indicates this market is likely to remain under pressure as inventory gradually increases and buyers explore alternatives in the broader luxury convertible space.
