2005 Maserati MC12 Stradale - $5.2m

Hammer price was $5,202,500 making this car the most valuable modern Maserati sold at auction.

One of 50 MC12 Stradale road cars built to homologate Maserati's FIA GT1 racer. Ferrari Enzo-derived, naturally-aspirated 6.0-liter V12 delivering 630 horsepower and 481 lb‑ft of torque. Finished in Bianco Fuji pearlescent white with blue accents over a Blu leather and BrighTex fabric interior. Showing just over 11,500 kilometers. Benefits from a $70,000 mechanical recommissioning by GTO Engineering in July 2025.

The Maserati's overwhelming superiority established it as the era-defining GT racing car of the 2000s and secured its place among most successful Italian GT cars in history. FIA regulations mandated the production of at least 25 road-going examples for homologation in GT1-class racing. Maserati fulfilled this requirement by building 25 cars in 2004, followed by 25 examples for 2005, creating a total production run of just 50 road cars—bolstered by a dozen further MC12 Versione Corse track-only variants. This limited production made the MC12 rarer than the 400-unit Ferrari Enzo upon which it was based.

The road-going MC12 Stradale was centered on the 6.0-liter Tipo M144A V12 engine derived from the Enzo, featuring double overhead cams, four valves per cylinder, and dry-sump lubrication. In Maserati tune, the powerplant produced 630 horsepower at 7,500 rpm and 481 lb-ft of torque at 5,500 rpm. This powerplant was mounted amidships in a carbon-fiber monocoque chassis incorporating Nomex honeycomb sandwich construction. Suspension was double wishbones with pushrod‑actuated coil‑over dampers at each corner, and Bosch electronic aids—including ABS, EBD, and traction control. This worked in concert with massive Brembo brakes (six‑piston fronts and four‑piston rears).

Chassis number 12095 was completed in 2005. It crosses the block at the Monterey Jet Center 2025 with an estimate of $4,800,000 to $5,500,000. Here.

1969 Chevrolet Camaro ZL-1 - $825k

Behold the mighty 1969 Chevrolet Camaro ZL1, appearing at Mecum Kissimmee in 2021. The 1969 Camaro with the uber rare, all-aluminum, 427-cubic-inch ZL-1 big-block was designed for racing. Chevrolet rated the ZL1 at 430 hp @ 5200 rpm and 450 lb-ft @ 4400 rpm. Dyno tests of factory ZL1s revealed their output was more in the 550hp range. 69 ZL-1 Camaros were built.

First. Most powerful. Quickest. One Chevy combines them all: the 1969 Chevrolet ZL1 Camaro. It went a step beyond the 427 Yenko and even the mighty L88 Corvette. A batch of '69 Camaros came with a version of the 427-cid V-8 used by the all-conquering Can-Am Chaparral. This was another very special Central Office Production Order. COPO 9560. These are the rarest of all 1969 Camaros.

The 427 was called the ZL1. It was similar to the most-potent iteration of the aluminum-head L88, but it was the first production Chevy engine to also have an aluminum block. It had a 430-bhp factory rating, but was well over 500 bhp. All this came at a price: $4,160 for the ZL1 engine alone, pushing the car's sticker to a ridiculous $7,200.

Two 1969 ZL1 Camaros were offered as a matched pair in 2018. Numbers 18 and 30 of the 69 Chevy built. The pair made $1.2m.

This 1969 ZL-1 sold for $1,094,500 at Barrett-Jackson’s Scottsdale sale in 2020. In 2017 the car changed hands for $770k.

The only Camaro to sell at auction for seven figures has it's original engine. The ZL-1 featured rectangular-port, open-chamber aluminum heads, and a forged crank, connecting rods, and pistons. It featured a solid-lifter camshaft.

1958 Edsel Citation Convertible - $173k

Known as the Solid Gold Edsel. 1 of 930 Citation Convertibles built for 1958 with fewer than 15 restored examples known to exist. The only known fully restored Citation Convertible ordered in Gold Metallic paint. Purported to have been previously owned by Robert Horton, star of the hit television series “Wagon Train”, which was sponsored by Edsel during 1958. Stored in a Chicago warehouse from 1978-2019 when it was acquired by the current owner from the collector's estate. Meticulous two-year frame-off nut and bolt restoration to factory specs using the original factory assembly manuals and NOS parts. Less than 30 miles since completion. Only 28,000 miles prior to restoration.

410 CI V-8 engine rated at 345 HP and 470 lb-ft of torque. Teletouch pushbutton transmission with shift buttons located in the center of the steering wheel. Optional exterior dress-up package. Illumination group. Signal-seeking radio with discrete FM chip. Original OEM spotlight. Rare power chassis lubrication system which is operated by a button on the dashboard. The Citation was the top Edsel model and was built on the large Mercury platform. In total, 9,299 Citations were produced by Edsel in 1958 with 930 convertibles.

The 1958 Edsel was introduced with much fanfare as a unique and innovative car, but ultimately became a massive failure. Reasons included poor marketing, design missteps, a depressed economy, and absolutely terrible build quality. Only around 100,000 Edsels were sold over its three-year production run. The car appeared at Mecum.

1971 Ferrari 365 GTS/4 Daytona Spider - $2.2m high bid

61,748 miles. 4.4L/352 HP V-12. 5-Speed Manual. Rosso Chiaro over tan interior. The 1971 Ferrari 365 GTS/4 Daytona Spider is highly coveted. The classic grand tourer is renowned for its performance and elegant design. 122 examples were factory-produced, making them highly sought after and collectible.

Some Ferrari are more desirable than others. Near the very apex is the 365 GTS/4 Daytona Spider. It is a car that needs no introduction to Ferrarista.

The car failed to sell on an estimate of $2.5m to $3m at Mecum.

5 muscle cars that lost their mojo

Collectible muscle cars have enjoyed a spectactular run-up in prices. Now some are falling in value faster than others. Hagerty reveals the biggest losers.

1969–70 Ford Mustang Mach 1: -12%. Ford introduced the Mach 1 package for 1969. Only available in SportsRoof configuration (previously fastback), the Mach 1 was a huge success. Engines could be optioned with everything from a two-barrel 351-cubic-inch V-8 to a 428 Super Cobra Jet. They’re popular and abundant. Lately less popular with the Cobra Jet taking the biggest hit.

1970–71 Plymouth Hemi Cuda Hardtop: -11%. In 1970, Chrysler launched its E-body platform with the all-new Dodge Challenger and third-generation Barracuda. A standard 383 car is expensive and desirable, a 440 six-barrel is highly sought after while Hemi Cudas are top of the pecking order. They are among the leading blue-chip muscle cars. There has been a softening in Hemi values, and a knock-down effect has occurred.

1973–74 Pontiac Trans Am Super Duty: -10%. While the muscle era had ended, Pontiac introduced a brand-new performance engine that revived the Super Duty name for 1973. For Pontiac fans, 455 SD–equipped cars are some of the most sought-after Firebirds, with just 1295 Formula and Trans Am cars produced over two years. While the Formula 455 SD is rare, with 100 total, Trans Ams are fairly common. Prime examples are changing hands for lower prices.

1966–67 Chevrolet Chevelle SS 396: -9%. By late 1965 Chevrolet had begun to be a player with the Z16-code 396 V-8 it shoved into the Chevelle Super Sport. By 1966, the Chevelle SS would be equipped with a 325-horsepower 396 big-block engine standard, with options taking it up to 375 hp. This finally put the Chevelle on track to play with the big boys. Chevelle SS 396s from 1966–67 enjoyed a quick rise in 2022. Things changed in the spring of 2025 and values are dropping.

1970–72 Chevrolet Camaro Z/28: -6%. Good for 360 horsepower in 1970, the Z/28 continued a winning combination of power and handling. Model-year 1972 would be the final year for the LT1-powered Z/28s. Z/28s remained steady performers, with values fluctuating little. Q1 2025 however has seen sale prices falling for 1970–72 Z/28s.
