There's an easy version of this market report, which is "everything's down, it's a crash, batten the hatches." There's a harder version which is what the numbers actually say, which is that H1 2026 has been the most selective UK classic auction half-year in roughly a decade. Money is still in the room. It is paying close attention to estimates, condition, paperwork and provenance, and it is walking when those don't line up. That distinction matters for buyers, sellers and owners trying to value what they have.

The data below covers Bonhams Cars (UK), Iconic Auctioneers, H&H Classics, Brightwells, Manor Park Classics, Mathewsons and the Hagerty UK Price Guide, January through May 2026. A small set of houses haven't yet published H1 totals; where that's the case it's flagged.

The top-line picture: prices flatter, sales harder

Hagerty UK's Best of British index, the broad gauge of how British classics are tracking, is at its lowest reading since the index launched in 2018, sitting at just over 80% of the 2018 baseline. That's an eight-year low on the headline number that most owners of British cars instinctively look at.

The underlying twelve-month-rolling data tells the same story. Nearly 80% of UK classic car values either fell or held flat in the twelve months to December 2025, the data set feeding the H1 2026 commentary. Of the modern-classic categories, broadly post-2000, only Porsche, Mercedes-Benz and Ferrari posted year-on-year growth. Every other modern-classic marque was flat or down.

The worst performer by marque was Jaguar at minus 21.4%, dragged heavily by a £3.6 million reduction in the mean value of the XKSS. That's a single-car-class effect, but it filters down through the rest of the Jaguar curve. XKs and E-Types of the right vintage have softened in lock-step, and the Series 3 E-Type 2+2 Coupe is now occasionally trading sub-£32k. Iconic sold a 1973 example at the Supercar Fest sale on 16 May for £31,500, which would have been an aberration five years ago and is now an unremarkable result.

The HAGI Top index (50 benchmark models from 19 marques, the long-running gold standard for blue-chip collector cars) has also continued its slide since the 2024-25 peak. Mid-market Mercedes "Pagoda" SLs and standard 911 variants are reportedly down 20-30% over that window. Hard Q1 2026 readings are subscriber-only and not in our hands, but the trend direction is consistent with everything the salerooms reported.

The sell-through split

The most useful single data point in any half-year is sell-through, how many of the lots brought to auction actually found a buyer. H1 2026 sell-through split sharply along two lines: volume versus premium, and well-presented versus optimistically estimated.

Volume-led, sensibly-estimated houses cleared rooms. Mathewsons' three-day classic vehicle sale in March (the kind of mixed sale where lot 47 is a £150 Toyota Hi-Ace and lot 240 is a £36k Triumph Dolomite) recorded a 98% sell-through rate on £1.79 million total. Iconic Auctioneers' Race Retro collectors' cars sale in February cleared 93% of 150 lots at £7 million across all three sessions. H&H's Pavilion Gardens Buxton sale in April booked £1.6 million and shifted a 1924 Rolls-Royce Silver Ghost that needed restoration for £37,125, well over its low estimate.

Premium and competition houses had to work harder. Bonhams' Goodwood Members' Meeting in April totalled £3.06 million across 78 cars at a 71% sell-through rate, perfectly respectable as a number, but with 33% of the catalogue selling under low estimate and only 19% over high. The 2000 Porsche 911 (996) GT3 RSR, a Daytona class winner with an estimate of £190,000 to £250,000, failed to meet reserve. The Iconic Race Retro competition cars sale managed 60% sell-through with eight £100,000-plus competition lots passing in, including an ex-Rob Walker 1954 Connaught Type B and an ex-John Price Renault 5 Maxi Turbo.

Rob Hubbard of Iconic put it bluntly in the post-sale notes: "The market is selective, but when cars are presented properly, estimated sensibly and backed by complete history, buyers respond." That is the through-line of the half-year in a sentence.

What's holding up: Japanese young-timers, hot hatches, late air-cooled

The categories with the cleanest tailwinds in H1 2026:

• 1990s and early 2000s Japanese performance cars. Iconic sold a 1998 Subaru Impreza 22B-STi for £187,875 at Race Retro, 25% above the high estimate and believed to be a UK record for a non-McRae 22B. A 1996 Honda NSX-T (manual) made £73,125 at Sywell, 33% over the high estimate. The R34 GT-R market remains strong even where individual cars stall on the day.
• Hot hatches and homologation specials. The Hagerty Hot Hatch and RADwood indices are the only two showing meaningful year-on-year growth. The 1987 Renault 5 Turbo "Superproduction" ex-Erik Comas made a live-auction world record of £331,895 at Race Retro. A 1991 VW Golf GTI Rivage Cabriolet set another at £36,000. Ford Cosworths still trade strongly though, in Iconic's read, "with less of a bidding frenzy" than 2024.
• Late air-cooled and early water-cooled Porsche. The 993 Carrera 2 is still hitting £60k-plus at Iconic; a 1996 example made £61,875 at Sywell. The 911 996 C2 3.4 is on Hagerty's 2026 Bull Market List with the highest collectability score of any car on the list, despite a small five-year value decline. Buyers are positioning.
• Hypercar-era moderns (selectively). The 1988 Lamborghini Countach 5000 Quattrovalvole made £512,500, the 2020 Ferrari 488 Pista Piloti went pre-sale at £489,166, and the 2002 Lamborghini Murciélago manual hit £264,500 at Bonhams Goodwood. Manual Murciélagos are running 18% above high estimate; manual-gated supercars broadly are the strongest single sub-category in the modern space.

What's softening: pre-war British, Jaguar broadly, early air-cooled

The categories where buyers have stepped back hardest:

• Pre-war British, broadly. The headline Best of British index is at its eight-year low and the slow drift down has accelerated in the twelve months to December 2025. Riley, Lagonda, early Bentley and pre-war Rolls-Royce have all softened by mid-double digits, with the exception of properly significant cars with strong provenance.
• Jaguar across most of the range. Minus 21.4% as a marque is a striking number, and XKSS is doing the heavy lifting on that, but it filters into XK150s, Series 3 E-Types and even later XJS values. The 1959 XK150 SE FHC at Buxton at £50,062 is a reasonable result; five years ago it would have been more.
• Lancia Delta Evo II and the 1990s rally-replica market. Iconic's reporting flagged Evo II prints at £138,133 at Race Retro versus £200,000+ at the peak. The cars haven't changed; the bidder pool around them has thinned.
• Pre-1968 Porsche 356 and very early air-cooled. The headline 1955 Porsche 356 (Pre-A) Speedster at Iconic Supercar Fest with an estimate of £230,000 to £270,000 failed to sell. Iconic flagged it explicitly as evidence of "further air-cooled and 356 cooling." Not a crash, but a noticeable correction from the 2022-23 peak.
• Competition cars without the right paperwork. Eight £100k-plus competition lots failed to sell at Race Retro alone. Where the car's history isn't watertight, the discount the room expects is larger than the seller is yet willing to wear.

Hagerty's 2026 Bull Market List in context

Hagerty UK published its annual ten cars to watch list in January. The list is a five-year view, not a six-month one, and the names tell the same story as the H1 data:

The two big gainers, F430 and Supra A80, are the modern Japanese and modern Italian story repeating. The 996 has the highest "collectability" score on the list despite a flat-to-down recent run; Hagerty is calling the bottom on it. The pre-war British names on the list (Riley, Viva, MGA) are explicitly there as "watch lists"; Hagerty is flagging them as undervalued, not as confirmed up-trends.

Why the data feels worse than the room does

If you've been at any of the UK fixtures over the last five months, you'll have noticed the contrast: the data reads softer than the rooms have felt. Race Retro at 93% on the collectors' sale, H&H's record motorcycle sale at the National Motorcycle Museum (£1.8 million across 301 lots, the house's biggest two-wheel sale ever), Mathewsons at 98% sell-through: these are robust numbers. The salerooms have been busy.

Three things explain that disconnect:

1. The data is dragged by a small number of very high-value cars softening hard. Jaguar's headline minus 21.4% is heavily an XKSS effect; a single car class moving down £3.6 million in mean value shifts the marque-level data well below what the median Jag owner has experienced.
2. Sell-through is healthier than estimate-realisation. Cars are selling, but more often at the low end of their estimate band than the high end. That's good news for sellers prepared to be realistic; it's bad news for headlines.
3. UK-to-US export volumes are down 14% to a six-year low, removing some of the strongest underbidder pressure from the upper end. Land Rover is the dominant export category at 24.8% of the total, which keeps Defenders and Range Rovers Classic firm; the rest of the export curve has thinned.

What to watch for the rest of 2026

The second half of the year carries the heaviest UK auction calendar of the cycle:

• H&H's flagship Kelham Hall sale on 17 June with a 1965 Ferrari 330 GT 2+2 at £180-220k and a 1950 Jaguar XK120 Roadster at £80-100k. Strong test of where the upper-middle Italian and British numbers actually settle.
• Anglia's two-day Norfolk classic sale from 20 June with a 1959 Aston Martin DB4 Series 2 LHD at a quarter-of-a-million-pound estimate.
• Bonhams Goodwood Revival sale in September. The 2025 Revival sale reportedly hit its lowest total since 2016. Whether 2026 reverses or extends that trend will be one of the most-watched data points of the year.
• The Iconic Sale at the BRDC Classic on 24-25 July, a first-running event at Silverstone, and an interesting consignment test in its own right.
• RM Sotheby's London Auction on 31 October at The Peninsula London, the year's flagship UK boutique sale, tied to London-Brighton Veteran Run weekend.
• Bonhams Bond Street on 11 December with a 1928 Mercedes-Benz 36/220 S-Type Sports Tourer at £1.25-1.75 million, ex-Sir Peter Ustinov. Year-end signal at the top end.

Our updated 2026 auctions page carries the full list of forty UK sales between 25 May and 31 December. If you're tracking specific marque values, the published catalogues from H&H, Iconic and Bonhams over the next twelve weeks are where the next reliable data points will come from.

The short version: H1 2026 has been a year for buyers, not for sellers expecting last-cycle estimates. The summer is when we find out if Q3 confirms the trend or breaks it.
