The Iso Grifo A3/L was designed by Giotto Bizzarrini for Renzo Rivolta. Styled by Giorgetto Giugiaro at Bertone, the A3/L coupe had an aggressive, muscular stance. They even developed an alloy-bodied race car, the incredibly sleek A3/C. This was the convertible variant of the road car – the lone drop-top prototype.

It says it has a “Corvette engine” – later Grifos got a 5.4-liter Chevrolet 327 V8. So who knows I guess (but it sounds like it’s a 427). Buy it and surprise yourself. This car was initially shown at the 1964 Geneva Motor Show and was later sold to an American. It came into its current collection in 1980 and has been hidden away since.

By 1965 things had soured between Bizzarrini and Rivolta, with the former going on to produce the Bizzarrini A3/C, and Rivolta selling the Iso Grifo GL. This car has an estimate of $700,000-$1,000,000. More info can be found here.

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 Grifo GL

1968 Iso Grifo GL Series I

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 Grifo A3/C

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.

Gooding Scottsdale Highlights 2012

Gooding & Company’s Scottsdale auction featured some major cars selling for some major cash – $39,833,900 all told. It was also one of the more successful auctions in recent memory, with only two cars going unsold for not meeting their reserves. Top sale at this auction was a 1955 Mercedes-Benz 300SL Alloy Gullwing. Mercedes-Benz built 29 aluminum-bodied 300SL coupes and this is number six. This is as desirable as Gullwings come and it exceeded it’s estimate by $1.5 million, selling for $4,620,000.

Also, somewhat shockingly, every car we featured here on this site from Gooding’s auction sold. The 1930 Duesenberg Model J Disappearing-Top Convertible Coupe sold for $2,640,000, which was the third highest at the sale. Second place went to the 1959 Ferrari 250GT California Spider – a car that Gooding seems to find one of for each of their sales. Where are these things coming from? It brought $3,905,000.

Other million dollar sales included the 1971 Lamborghini Miura P400 SV we featured a few weeks ago, selling for $1,100,000. There was also this matching-numbers 1967 Ferrari 275 GTB/4 which sold for $1,200,000.

The final million dollar sale went to this awesome 1965 Ferrari 500 Superfast which was hammered away for $1,100,000. It’s one of only 36. It has 400 horsepower – more than just about every muscle car of its day – but the shape of it is so much sleeker than a GTO or Mustang. Super fast indeed.

Two cars that Gooding promoted heavily in the lead up to the auction also showed well. There was a brilliant green 1971 Maserati Ghibli 4.9 SS Spyder which split its pre-sale estimate, selling for $880,000.

Also, this 1969 Iso Grifo 7 Liter – one of only 66 Grifos built with the 7.0 liter V8 making more than 400 horsepower. A 1960s supercar in crazy purple paint? Yes, please. It satyed nearer its lower estimate at $352,000.

Another purple exotic was the 1927 Bugatti Type 38A Tourer by Figoni that we featured. It brought a hefty $495,000. Among our other featured cars, the 1967 Trident Clipper V8 was a steal, missing its estimate entirely and selling for $39,600. Our final feature car was an unbelievable 1937 BMW 328 which was well bought for $517,000. Another rare BMW sold there too, this 1958 507 Roadster. While not as good-looking as the car offered by RM across town, it still rang up a hefty $962,500.

Other interesting sales included a 1938 American Bantam Roadster which far exceeded its pre-sale estimate of $35,000-$55,000 and ended up selling for $90,200. Cute sells.

There was also an ultra-rare 1969 Chevrolet Corvette L88 Coupe. The car is a survivor – unrestored in Monaco Orange with less than 18,000 original miles. This was the king of Corvettes in 1969 – the L88 option got you more horsepower than a ZL1. This car was rated at 430 horsepower but likely put out more like 560. It doesn’t play around. And neither does its hammer price of $451,000.

And from the fun-file: this 1963 Volkswagen Beetle Sunroof Sedan – which sounds pretty normal from the name of it. Until you see it:

This car was featured in the film Herbie Goes to Monte Carlo. There are desirable, well-optioned Volkswagens, but people are going to recognize this one. And for $66,000 ($15,000 below it’s pre-sale estimate) it’s going to be a lot of fun. For full results click here.
