June 2026: The R129 Rises, the Continental GT Collapses

Nineties Mercedes roadsters are the month's quiet story in Britain, while America decides depreciation applies to Bentleys after all.

United Kingdom

Forty-four confirmed sales, a median of £15,750, and the pattern is nineties nostalgia doing its usual thing — except it's now the R129 SL leading the charge. Fourteen cars traded at a median of £13,722, up 55.9% year-on-year. That is a proper sample and a proper move. The R129 was, for a decade, the definitional 'good used Mercedes': overengineered, slightly gauche, dirt cheap. It is no longer dirt cheap. The classic Beetle (+52.4%, n=6) and Range Rover Classic (+40.0%, n=5) are thinner tapes but tell the same story about buyers chasing shape and silhouette over anything resembling driving dynamics. At the top of the market the Porsche 356 (+38.4%, n=8, £92k median) and Ferrari F355 (+38.4%, n=6, £86.5k) both firmed — sensibly, given how long they'd stagnated.

The droppers are more interesting. A Caterham Seven at £16,000 median, down 40.7% on seven cars, suggests the trackday-toy premium of the pandemic years is finally bleeding out. The Rolls-Royce Phantom VII (-37.3%, n=6) and Bentayga (-35.0%, n=5) confirm what anyone servicing one already knew: modern super-luxury depreciates like modern super-luxury. The XJ-S at £9,850 (-34.9%, n=9) is the one that stings — a decent sample size, a car with genuine presence, and it's being given away.

The individual results tell you where the actual money went: a 1969 Pagoda at £80,500, a 1994 XJ40 Sovereign at £66,250 (yes, really), and another Pagoda at £46,500. The-Market cleared the room this month.

Australia

Zero confirmed sales in the June window in our dataset, which happens and which we'll flag rather than dress up. The twelve-month trailing picture, however, is worth reading. The Land Rover Series I is up 41.8% (n=6, A$32,250) and the GC8 WRX STi keeps climbing — fifteen cars, A$47,000 median, +33.9%. That is the healthiest sample in the Australian mover list and the clearest signal: the JDM-adjacent nineties rally cars are still finding new money. The Diablo at +25.1% on nine cars and A$720k is doing what analogue Lamborghinis have done for four years running.

On the other side, the R35 GT-R is down 55.3% on six cars. Small sample, huge move, and consistent with what we're seeing globally as R35 supply catches up with the wave of buyers who wanted one at any price in 2022–2023. The NA1 NSX (-30.0%, n=5) and R34 (-18.0%, n=8) round out a Japanese performance segment that is, politely, taking a breather. The Defender 90 slipping 16.3% while the Series I climbs 41.8% is the sort of internal contradiction that makes the Land Rover market such a reliable source of comedy.

United States

Three hundred and twenty-three sales, median $23,000, and the movers list reads like a Ferrari dealer's holiday card. The 360 Modena is up 39.2% (n=14, $108,680), the F430 up 35.5% (n=15, $164,000), and the 930 Turbo up 37.2% on a very solid eighteen cars at $207,500. These are not thin tapes. The 2005 Ford GT continues its serene ascent — seventeen sales, $627,000 median, +34.9% — and the Hemi Road Runner (+35.3%, n=10) shows muscle isn't dead, it's just selective.

And then the droppers, which are where the month gets genuinely interesting. The Bentley Continental GT W12 is down 54.0% on twenty-four cars — that is a large, clean sample and a brutal number. The market has decided the W12 Continental is a used car, not a classic, and it's pricing accordingly. The C3 Corvette (-42.4%, n=40) is the largest sample on either side of the ledger this month and confirms what C3 owners have been denying for a decade. The Viper ACR down 45.7% on thirteen cars is the one to watch: a car with genuine motorsport bona fides retreating this hard suggests the modern-analogue-hero premium is being repriced across the board. Note also the Porsche 356 down 46.5% in the US (n=23) while it rose 38.4% in the UK — same car, opposite tape, worth chewing on.

At the top: a $766k Aventador Ultimae, a $548k GT2 RS Weissach, and a $375k 356A Carrera. BaT is still where the seven-figure adjacent cars clear.

Thesis

The defining pattern of June is bifurcation by generation: the analogue nineties (R129, 360, 930, GC8) are still absorbing capital while the modern-luxury and modern-hero cars (Continental GT, Bentayga, Viper ACR, R35) are being marked down hard on healthy samples. The Porsche 356 splitting +38% in Britain and -46% in America on the same month is the single strangest number in the dataset, and probably says more about currency and buyer composition than about the cars themselves.
