Grifo Targa

1970 Iso Grifo Series I Targa

Offered by Bring a Trailer | December 2024

Photo – Bring a Trailer

The Iso Grifo is perhaps the most muscular of all of the Italian/American hybrid muscle cars. Sure, it’s a two-door coupe and a sports car. But it has angry lines and big American V8s. That’s a muscle car.

The Grifo has an interesting history, as discussed here, and went on sale in 1965. This is one of 330 Series I cars built, just 14 of which were targas. Power is from a 5.7-liter Chevrolet V8 rated at 300 horsepower.

It was cosmetically overhauled in Europe in the early 2000s and received mechanic work in the years following its importation to the U.S. These are very rare big-dollar cars. You can read more about it here.

Iso Fidia

1973 Iso Fidia

Offered by Bonhams | Greenwich, Connecticut | June 4, 2023

Photo – Bonhams

Here is a rare 1960s European four-door sedan in the vein of the Monteverdi 375/4, Maserati Quattroporte, and Aston Martin Lagonda. Iso was no Maserati or Aston Martin (even in the ’60s). It was more on par with Monteverdi as a small-batch car manufacturer.

The Fidia sedan was sold between 1967 and 1975, and in that time, just 192 were produced. Each one had styled by Giorgetto Giugiaro at Ghia and was powered by an American V8. In this case, it’s a 5.8-liter Ford V8 rated at 330 horsepower. A GM unit was also available on earlier cars. Only 35 had the 351 Cleveland.

This car has been on static display for the last 10 years and will require work before it is roadworthy. But I feel like saying that a 50-year-old exotic Italian sedan from a cottage industry manufacturer “requires work” is somewhat a given. The pre-sale estimate here is $25,000-$40,000.

Update: Sold $17,920.

Iso Rivolta GTZ

2021 Iso Rivolta GTZ

Offered by Mecum | Kissimmee, Florida | January 6-16, 2022

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.

One-Off Iso Truck

1966 Iso Centomila

Offered by Finarte | Online | November 29, 2021

This may look like a Haflinger built by a refrigerator company but… oh wait, that’s sort of exactly what it is. When Iso Rivolta shifted from appliance to motorcycle manufacture after WWII, they also expanded into other territories, including microcars and sports cars.

So why not give off-road vehicles a go? This was the only one built, and it’s powered by a Fiat inline-twin sourced from a 500 Giardiniera. Apparently Iso sent it to Fiat for evaluation, and they liked it and wanted to take over, but Renzo Rivolta refused.

So the little truck returned to Iso, where it was used as a service truck. It’s the only one like it, and it’s expected to sell for between $21,500-$32,000. Click here for more info and here for more from this sale.

Update: Sold $25,057.

Iso Grifo GL

1968 Iso Grifo GL Series I

Offered by RM Sotheby’s | Elkhart, Indiana | October 23-24, 2020

The Grifo GL is a Bertone-styled Italian muscle car. It was designed by Giotto Bizzarrini and styled by Giorgetto Giugiaro. It was introduced in 1963, and a racing variant, the Grifo A3/C, debuted alongside

The grand touring Grifo was slightly restyled before entering production as the Grifo GL. Meanwhile, Bizzarrini got irritated, took the A3/C, and went and produced it as the Bizzarrini 5300 GT.

The Grifo GL road car soldiered on under the Iso marque. Early examples were powered by 5.4-liter V8 from a 327 Corvette that made 350 horsepower. That’s what this car originally had. But later Grifos received a 7.0-liter Corvette 427 V8 advertised at 435 horsepower. It’s what this car currently has under that mean hood with a very serious-looking vent.

This car received a six-digit restoration in 2005 and is now offered at no reserve. Check out more about it here and more from RM here.

Update: Sold $500,000.

Iso Rivolta

1967 Iso Rivolta IR 300 Coupe

Offered by Bonhams | Paris, France | February 4, 2016

Photo – Bonhams

The Iso Rivolta is, obviously, a very good-looking coupe built by Iso between 1962 and 1970. The IR Coupe was offered in two forms, the 300 and the 340. It was the first car the company introduced after their famous Isetta, marking the move from microcars to powerful tourers, sports cars, and sedans.

The engine is a 5.4-liter V-8 from Chevrolet making 300 horsepower. Top speed is 135 mph. The styling was done at Bertone by Giorgetto Giugiaro and the chassis was was designed by Bizzarrini. It’s an Italian-American sedan. And a mean-looking one at that.

This car was restored two years ago and has spent its whole life in Italy. This was Iso’s best-selling model, with 797 built. This one should bring between $93,000-$140,000. Click here for more info and here for more from this sale.

Update: Sold $103,095.

Iso Lele

1972 Iso Lele

Offered by Coys | Frankfurt, Germany | September 26, 2015

Renzo Rivolta re-founded the Iso refrigeration company in 1953 as an automotive company. Motorcycles came first, followed by the iconic Isetta – which would go on to be licensed all over the world. But in the 1960s and 70s, Iso produced a number of high performance cars.

The Lele was the final new car introduced by Iso and would be the last to leave production (alongside a version of the Grifo). Two models of the Lele were offered – one powered by a Chevrolet engine and one powered by a Ford engine. This car uses the 5.7-liter Ford V-8 making 326 horsepower.

It’s a 2+2, meaning it will seat four – making it more of a grand tourer than a muscle or sports car. This car is all original and had one owner from new until 2014. Only 285 were produced between 1969 an 1974. 135 of the base Ford V-8 models were produced, the most of any Lele sub-model. This one should bring between $100,000-$125,000. Click here for  more info and here fore the rest of Coys’ lineup.

Update: Not sold.

Iso Grifo A3/C

1965 Iso Grifo A3/C Stradale

Offered by RM Auctions | Paris, France | February 4, 2015

Does this look like a Bizzarrini to you? It is. Kind of. Let’s start at the beginning: Giotto Bizzarrini left Ferrari after designing cars like the 250 GTO. He teamed up with Renzo Rivolta to design a followup to the Iso Rivolta GT. The car he came up with was the Iso Grifo A3/C. But at the same time, Rivolta was working with Bertone, who came up with the Grifo A3/L – which would become the Iso Grifo road car.

But Bizzarrini was designing his Grifo as a race car. And when Mr. Rivolta was trying to sell Grifo road cars, Bizzarrini was trying to drum up support for the race cars, which didn’t sit well with Rivolta. So they split. And Bizzarrini took his design and sold some as the Bizzarrini 5300 GT.

The car you see here was actually sold as an Iso Grifo A3/C in 1965. A few years later, after the two Italian men had parted ways, this car returned to Bizzarrini for updates and it was rebuilt to look more like a Bizzarrini 5300 GT (and given Bizzarrini badging). The engine is a 5.4-liter V-8 from a Corvette making more than 350 horsepower. It is mounted behind the driver, making this one of the first mid-engined cars.

Bizzarrini managed the construction of A3/Cs at Piero Drogo’s Carrozzeria Sports Cars where the early cars had riveted bodies. This is one of 20 riveted-aluminium cars. Combined production of the Iso A3/C and the Bizzarrini 5300 GT totaled to something between 100 and 150 cars, with Bizzarrinis making up the majority of them. This car was restored in 2010 and should sell for between $1,250,000-$1,850,000. Click here for more info and here for more from RM in Paris.

Update: Sold $1,186,220.
