I doubt that car is. They are holding values of either 3 or 12 million USD. Eve Saint Lauren has one. There are either 1 or 2 more in existence running, one being that silver above.
The airplane had a sad story. Don't read past here if you don't want to hear.
It wound up in a barn or storage place and bought by a Bugatti parts dealer. He took it and removed the magnesium engines (2) (Formula 1 specially cast for this plane) out and sold those, then removed most of the gauges and sold those as well. It ended up in Florida where said parts dealer lived(s). It was finally donated to the EAA and they restored the bird to a beautiful condition which you see today, but you will note that the real plane has no engines and most of the gauges are gone. Some are believed to be Jaeger gauges. Some we have no idea what they did or were, only holes in the cockpit where they went.
The plane was so advanced, it had automatics for deceleration, gear retraction, etc. The cooling system was ram air based in the wing roots and rudder faces. The engines were two Formula 1 Grand Prix engines (they were winning races for years), both engines super-charged, with their drive shafts fed through the cockpit from behind midships, into a gear box located up in the nose, which allows the props to spin in opposing directions.
Its all engine and wings and a space for a pilot. It is like something from Buck Rogers, a bullet shape like that. If it had run, which I doubt it ever did, as WWII and the invasion of France occurred during its construction, the engines together at high RPM would have sounded like banshees....! Ear pearcing banshees....!
It was found out that the air racing authorities had already denied its entry into air racing as it would have had 'no contest' in winning against anyone, especially the Messerschmitt air racers which were cleaning up the races back then over in Europe. But alas, the war.
