Iso is a name that goes back to some pretty sleek sports cars (or proto-supercars) of the 1960s and 1970s. They also produced what I’ve always considered to be Italian muscle cars, in addition to the original Isetta. The brand was revived in 2017 in collaboration with Zagato to introduce a Vision Gran Turismo prototype.

That led to a project dubbed the GT Zagato, or GTZ. The Rivolta family is still behind the cars, which are designed and built by Zagato. It’s based on a C7 Corvette Z06, but has a completely unique carbon-fiber body and shares no exterior bits with the Corvette, glass included. The supercharged 6.2-liter Z06 V8 makes 660 horsepower, enough to propel this very A3/C-esque design to 185 mph.

These are technically still in production, I guess, and in the last year they’ve built 19 of them. This is apparently the only one imported and registered in the U.S. Click here for more info and here for more from Mecum.

Update: Not sold, high bid of $700,000.

The 599 GTB Fiorano was Ferrari’s front-engine V12 grand tourer between 2007 and 2012. It spawned a few notable factory variants, including the HGTE (which was more of an add-on package), the XX (which was a track car), and the GTO (which was a road version of the XX). There was also the limited-edition drop-top, the SA Aperta.

Zagato, which had done similar things to the 599’s predecessors, the 575 and the 550, decided to do a limited run of modified 599s, dubbed the GTZ Nibbio (there were both coupes and spyders). Basically, they took a 599 GTB and re-sculpted the body to include their current weird design language, which consists of a rounded tail and two bulbous pointy bits on either side of the front grille. In this case, they also chopped off the roof.

The 6.0-liter V12 remains unchanged and is still rated at 612 horsepower. Only nine Nibbios were made, six of which were convertibles. Somehow this car was completed in 2020 and retains Zagato’s prototype serial number. You can read more about this car here and see more from RM here.

Update: Not sold.

The Ferrari 550 Maranello was produced between 1996 and 2002. In 2000, the company launched the 550 Barchetta, a convertible version that marked Ferrari’s fun new business of chopping the top and jacking up the price for a limited-edition model. Only 448 Barchetta examples were built.

This one was later customized by coachbuilder Zagato. It was actually developed with Ferrari as a convertible variant of the 575 GTZ, which itself was a Zagato-modified version of the 550’s followup car, the 575M Maranello. Because the 575 Superamerica (the 575’s expensive drop-top version) had yet to enter production, they backtracked to the 550 Barchetta to built the drop-top 575 Zagato.

When new, this car cost $1 million. It’s powered by a 478 horsepower, 5.5-liter V12. They planned to build five, but only three were completed. And this is the only right-hand-drive example. The pre-sale estimate is $640,000-$900,000, and you can read more about it here. See more from Bonhams in London here.

Update: Sold $769,393.

Coachbuilt cars are few and far between these days. Sadly, it’s becoming a lost art. But fortunately, there are still a few design houses out there that will custom fit a special body on the car of their customers’ choice. In this case, it happened to be a Ferrari 575M Maranello.

The 575M Maranello was the replacement for the very similar 550 Maranello. It debuted in 2002 and lasted through 2006. It uses a 5.7-liter V-12 making 508 horsepower. Top speed was a pretty awesome 202 mph. Ferrari built their own limited-run model: the 575M Superamerica with a retractable glass panel roof, which is a pretty cool car.

But not cool enough for Japanese Ferrari collector Yoshiyuki Hayashi, who custom ordered this specially-bodied, one-off 575M Maranello from legendary coachbuilder Zagato. The design hearkened back to the 250 GT Zagato and celebrated the 50th anniversary of the Ferrari 250. You should really check out more pictures on RM’s site here because this thing looks awesome from all kinds of angles (especially the back). You can also check out more from this awesome sale here. As far as price goes, I’m not sure – but it will be way cheaper than it cost originally.

Update: Not sold, high bid of $1,100,880.
