Road-going Le Mans racer features in latest instalment of talk show host's web series.
The Porsche Schuppan 962CR was a limited-run special built by race car driver Vern Schuppan, based on the Porsche 962 Le Mans race car he drove and owned with his team.
Just six are believed to have ever been made, including the first prototype, powered by a twin-turbocharged 3.3-litre flat six making around 600hp (447kW).
It's believed only one example – chassis #06 – resides in the United States, and the owner of that car, Matthew Ivanhoe, has kept it in as-new condition.
Before he brought it to the set of Jay Leno's Garage, Ivanhoe's 962CR had just one mile on the clock. After meeting and filming a segment with the famous talk show host, there's now "a few more".
