George Lucas was a huge gearhead, growing up in the Central California car scene filled with hot rods and foreign sports cars, not unlike this Porsche 718. Surround one with stormtroopers and the influence of cars on Star Wars becomes clear.
We knew there were other gearhead touches in Star Wars, like a race of desert people named after desert racing motorcycles. We already had the Millennium Falcon's inspiration worked out, but we never had any one thing to point to with the Landspeeder.
Obviously, we don't know for sure what the inspiration was for the Landspeeder, but when you look at it it's suddenly hard to imagine anything else.
It looks like a fun time.
