Collector Car Auctions July 9-12: Bugatti Chiron, Ferrari F50 & MoreIndependence Day fireworks have faded and Monterey Car Week is still more than a month away, which makes the long weekend of July 9–12, 2026 one of the quieter weekends of collector car auctions in 2026, per RM Sotheby's global auction calendar. There is no live docket from the biggest American or European houses this time around, but a trio of online sales bridges the four days, and the daily churn on Bring a Trailer and Cars & Bids keeps things from ever going quiet. Here is a look at everything crossing the block this weekend, plus a preview of who is saving their best metal for later in July.RM Sotheby's Runs Two Online Sales Through the WeekendRM Sotheby's has two timed online auctions overlapping the weekend, a continuation of the online-heavy pattern the house leaned on for the July 4th weekend as well. The Abu Dhabi Collectors' Edit: Materiality, a joint sale with Sotheby's spanning cars, watches, jewelry, and handbags, closes Friday, July 10. The automotive half is a tight three-car lineup topped by a 2018 Bugatti Chiron estimated between $2,850,000 and $3,500,000, with bidding sitting at $2,000,000 as of this week. A 1993 Mercedes-Benz 500 GE V8 (estimated $140,000–$250,000) and a novelty Ferrari 126C4 "Junior" child's car round out the automotive lots.Running the entire length of the weekend and beyond is Sealed July, RM Sotheby's monthly timed-bidding sale, which does not close until July 16. The headliner is a Ferrari F50 offered without reserve and guided at £5,000,000 to £6,000,000, joined by a 1972 Ferrari 365 GTS/4 Daytona Spider by Scaglietti (estimated €2,300,000–€2,800,000), a 2005 Maserati MC12, and a 1986 Riva Aquarama Special speedboat. The mix of a no-reserve Ferrari halo car against a private-treaty-style boat sale is a good illustration of how far RM's Sealed platform has stretched beyond just cars since it launched.Bonhams Keeps an Automobilia Sale OpenBonhams' live motoring calendar is quiet this weekend, but its online Summer Automobilia Auction, including the Robert Lusk Collection Part IV, runs July 6 through July 16 out of Guildford, England, with 171 lots of racing memorabilia, dealer signage, and motoring ephemera crossing the block throughout the window.Iconic Auctioneers' Charity Sale Wraps as the Weekend BeginsIconic Auctioneers, the rebranded Silverstone Auctions, closes its O2 Silver Clef Charity Auction on July 9, the first day of this guide's window, benefiting the music-therapy charity Nordoff and Robbins. It is a warm-up of sorts for the house, which returns with a much bigger docket later this month when Anthony Hamilton's £3 million personal collection heads to Silverstone on July 25.The Daily Churn: Bring a Trailer and Cars & BidsAway from the big-house calendars, these two collector car auctions sites never stop, with new lots closing every few minutes across the entire weekend. Among the vehicles moving through Bring a Trailer's docket this week are a 20k-mile 2019 Rolls-Royce Phantom, an original-owner 1978 Toyota Land Cruiser FJ40, a 1973 Ford Bronco with its numbers-matching 302, and a five-speed 1986 BMW 635CSi. Over on Cars & Bids, standouts include a rare five-speed 1993 Mercedes-Benz 300SL, an RB26-swapped 2001 Nissan Skyline 25GT Coupe, and a street-legal Porsche 917 replica built on a modern LS-powered chassis. Anyone new to bidding on either platform should read our collector's guide to bidding smart before jumping in, since reserve and no-reserve auctions behave very differently once the countdown clock starts.The Big Names Sitting This One OutFor collectors used to a live docket every weekend, this is one of the emptier weekends of collector car auctions all summer. Mecum's next stop is Harrisburg, running July 22–25. GAA Classic Cars is holding its next sale the same week, July 23–25 in Greensboro. Barrett-Jackson does not return until its Las Vegas sale in September, and RM Sotheby's next live auction is Monterey on August 13–15, the same week Broad Arrow debuts as The Quail's official auction partner. Bonhams' and Iconic's next major UK sales, Edinburgh and the Anthony Hamilton collection at Silverstone, both land later in July as well.Reading the MarketA Bugatti Chiron bidding well under its low estimate with just days to go is worth watching against the backdrop we described in our recent look at a two-speed collector car market, where the very top of the market keeps setting records while everything else softens. A no-reserve Ferrari F50 at RM's Sealed sale, by contrast, guarantees a result no matter where bidding lands, and will be a cleaner read on where the ultra-high end actually sits than an estimate-driven sale ever could be.AdvertisementAdvertisementEstimates and lot details reflect figures published by the auction houses at the time of writing and are subject to change.
