Tuesday on Modern Car Collector kept circling back to paperwork: a kit car whose VIN history did more for its price than its build, a Ferrari with a documented Atelier commission, a market brief where two nearly identical Corvettes split $148,000 on file strength alone, and a 35-year-old supercar whose comps now hinge on binders, not bodywork. In between were three fresh auction listings, a growing collection headed to Mecum Nashville, a giveaway deadline, and a Barrett-Jackson result that says more about where buyers are putting their money than the hammer prices alone. Here’s everything we published on September 15, in order, so you can catch up on anything you missed.
No Reserve: Mark Davis’s Raiders-Liveried 2021 Ferrari 812 GTS Is for Sale on Bring a Trailer

A 484-mile 812 GTS commissioned through Ferrari’s Atelier program by Las Vegas Raiders owner Mark Davis heads to no-reserve sale on Bring a Trailer. The V12 flagship’s back story is doing as much work as its spec sheet — celebrity ownership plus factory-documented customization is a combination the market keeps rewarding.
A Split-Window Corvette Stalled $148,000 Below One That Sold Last Week. The Spread Inside the Model Is the Real Signal.

Our daily market brief: two split-window Corvettes finish $148,000 apart, a GT3 Touring stalls at $285,000, a Tokyo-market Integrale Evo II clears $169,000, and RM Sotheby’s closes a no-reserve single-owner catalogue in Belgium. The spread inside one model is often more informative than any single result.
1970 Plymouth Superbird Heads to Carlisle Auctions: A Rare Factory Four-Speed Wing Car Hits the Block

A Lime Light green Superbird lands at Carlisle Auctions as a showcase lot. Factory four-speed wing cars in original color combinations are thin on the ground, and this one combines the options collectors chase most with the kind of finish that turns heads on the show field, not just the auction block.
Johnson’s Horsepowered Garage Collection Heads to Mecum Nashville 2026

A wildly varied lineup — vintage pickups, winged Mopar aero cars, resto-mods and modern supercars — heads to Mecum Nashville under one consignor’s banner. Collections built on a builder’s eye rather than a single marque tend to sell in pieces to very different buyers, which is exactly what makes them worth watching lot by lot.
1969 Ford Mustang Boss 302 Heads to the Block at Henderson Auctions

Finished in factory Bright Yellow with black accents, this Boss 302 heads to Henderson Auctions as a well-documented small-block icon. The 302’s reputation was built on the track, and buyers chasing this generation still pay a premium for panels and paperwork that back up the badge.
Win a Restomod 1965 Corvette Sting Ray: Enter the Dream Giveaway Before It Ends 9/17 for 5X Entries

The Dream Giveaway’s blacked-out restomod 1965 Sting Ray closes September 17. Modern Car Collector readers get 5X entries with code MCC5 — a reminder that the window is down to two days for anyone who has been putting this one off.
The Body Tag Tells the Real Story on This 809-HP 1963 Chevy II Nova SS

A Wegner-built supercharged LSA makes 809 horsepower in this Nova SS on Bring a Trailer. The dyno number gets the headline, but the Fisher body tag is the reason this build didn’t destroy any value — knowing exactly what the shop started with matters more here than the numbers it ended with.
Today in Collector Car History: The Bugatti EB110 Debuted 35 Years Ago Today, and Its Market Now Pays for Paperwork

The EB110 launched on September 15, 1991, Ettore Bugatti’s 110th birthday. Thirty-five years later, prototypes are approaching $3.8 million while ordinary production cars sit flat — a gap the anniversary makes easy to see and the paperwork alone explains.
A Modern Ford GT Outbid a Genuine Boss 429 at Barrett-Jackson Las Vegas — And That Gap Is the Real Story

At Barrett-Jackson’s Las Vegas sale, a 2019 Ford GT Lightweight Carbon Series topped the docket at $968,000 — ahead of a genuine Boss 429. A modern supercar outbidding a numbers-matching muscle car icon says less about either car and more about where collector money is actually flowing right now.
This K-1 Attack Isn’t Cheap Because It’s a Kit. It’s Cheap Because Nobody Wrote Down Who Built It.

A 2016 K-1 Attack on Bring a Trailer pairs an original Slovak design with a Honda VTEC four and a state-issued VIN. It closes out the day the way it started: this is a market that prices paperwork before it prices rarity, and a component car with a clean title tells that story as plainly as a $968,000 Ford GT does.
That’s the full slate for September 15. Check back through the day for new stories, or follow along as fresh listings and auction results come in.
