SEMA 2019: 1967 Iso Rivolta IR 300 Custom Coupe by Griot’s Garage

1967 Iso Rivolta IR 300 Custom Coupe by Griots Garage
Iso was an Italian automobile manufacturer that dates back to 1939. They began as an appliance manufacturer, and in 1948 began building motorcycles. In 1953 the company unveiled its first car: the Isetta, famously known as the “bubble car.” They licensed the design to several manufacturers including BMW, who went on to mass produce the car to worldwide fame.

In the early 1960s, Iso entered the sports car market with their first model, the Rivolta. They would later produce the Grifo, Fidia, and Lele models. All of these were low volume production cars, with just a few hundred examples built of each model.

Approximate Production Numbers:
Iso Rivolta: 797 units
Iso Grifo: 413 units
Iso Fidia: 192 units
Iso Lele: 285 units

Iso automobiles combined beautiful Italian design with powerful American engines from Chevrolet and Ford. They were expensive and luxurious models for the rich and famous. The Fidia S4 sedan briefly held the title of World’s Fastest Sedan in the late 1960s. Unfortunately, the market for gas guzzling luxury automobiles evaporated after the 1973 oil crisis, and the company ceased operations permanently in 1974.

I have something of a soft spot for these niche Italian cars, which are much less known than brands like Lamborghini, Ferrari, and Fiat. Regular readers of this site may have even seen my previous posts about the Iso Lele and Iso Fidia S4 in the past. You can imagine my surprise when I walked into the Griot’s Garage booth at the 2019 SEMA Show and saw this gorgeous Iso Rivolta IR 300 coupe. It was a rare sight at an event that is dominated by American muscle cars like the Chevrolet Camaro and Ford Mustang.


This particular car belongs to Richard Griot, who founded Griot’s Garage in his home garage in 1988. Griot’s Garage has grown to become a powerhouse brand that offers wash, polish, wax, and other automotive detailing products. This 1967 Iso Rivolta has received a full restoration by J&L Fabricating of Puyallup, WA.

Back in 1967, the Rivolta coupe was offered with two engine choices: a Chevrolet small block V8 making either 300 or 340 horsepower. This car has been upgraded with a GM Connect and Cruise LS7 7.0L V8 engine, which produces 505 horsepower. It is coupled to a Tremec T-56 Magnum 6-speed manual gearbox.

The car has been given a full resto-mod treatment, which means that it does more than just go fast in a straight line. It can also handle corners like a modern car, thanks to an Art Morrison suspension and rear subframe with Camaro rear end. Brakes have also been upgraded to Wilwood 13-inch disc brakes.

The car rides on a set of EVOD Industries 17-inch custom wheels wrapped in Pirelli P-Zero tires, which measure 235/50-17 up front and 285/40-17 in the rear. Other upgrades include a Borla custom exhaust, a gorgeous interior, and a PPG Black paint job done by Jon Beyers Customs.

While it may have looked unfamiliar to the Chevy and Ford guys, this car is essentially an American muscle car in an Italian suit. I really enjoyed seeing this car at the SEMA Show and applaud the owner for building something different than yet another Camaro or Corvette.

1969-1974 Iso Rivolta Lele


When thinking about Italian cars, brands such as Ferrari and Lamborghini probably come to mind. But there are many, many others – Maserati, Fiat, Lancia, Abarth, Alfa Romeo, to name several. But there are also the lesser-known Italian marques like DeTomaso, Intermeccanica, and Iso.

Today’s post is about that last one – Iso. Founded in 1939, they made cars and motorcycles in Italy through 1974 when the company went bankrupt. I have previously written about the Iso Rivolta Fidia S4, which was briefly the world’s fastest 4-door car when it was introduced in the late 1960s. Around the same time, Iso was also manufacturing this car, the Lele. With its 2+2 layout, it would likely have been a competitor to the Lamborghini Espada, another Grand Tourer. The Lele was one of the last models that Iso made before shutting down production entirely.


I stumbled across this car at the Barrett-Jackson 2019 collector car auction in Scottsdale. Funny enough, the car was not part of the auction, but rather parked outside in the parking lot! It’s not often that I see a car I cannot identify, and I thought at first it might have been another Lamborghini Islero, as they have quite similar body lines. With no visible badging, I went in for a closer look. The only emblem was a small Iso Rivolta badge on the hood.
These are extraordinarily rare cars, with only 285 produced during the five year production run. The chances of simply happening upon one in a random parking lot are unbelievable! After some research online, I learned that the cars came with either small block Chevy or Ford engines. I am not sure which engine this car has, though the split is pretty even with 125 of them being Chevy powered and 160 of them Ford powered.

The Hagerty price guide places the value on these cars at about $30,000 in Fair condition to $70,000 in Concours condition. For those who dream of owning an Italian sports car but with a Ford or Chevy budget, the Lele may be a great alternative to the more common Italian brands. I think it is a super neat car and would love to own one!

1967-1975 Iso Rivolta S4 Fidia

There is a gathering in Scottsdale on the first Saturday of each month called Cars and Coffee. This informal car show is open to all makes and models of vehicles, so you never know what might roll in.

It was here that I first spied the Hudson Italia, not knowing how rare or valuable it was. I kicked myself later for not taking more pictures of it. Well, I made the same mistake with this car. Not recognizing it, I foolishly took a single picture and moved on. Now I wish I had taken more!

This huge sedan is an Iso Rivolta S4 Fidia, and its claim to fame is that it briefly held the title of “World’s Fastest Four-Seater” in the late 1960s. Only of these cars 192 were built, so it’s pretty damn rare!
