Tootin' Their Horns

Tonight was members only at the Art Museum for another look at cars shaped for speed. This time with the hoods up for a look at the motors.
This is a 1939 Panhard & Levassor (you could have fooled me, too). The Extra is a Bugatti. Its body is made of magnesium, light weight, but too flammable to weld, so they rivetted it together.
