I would consider a Willys coupe. Thank you. I am a bit enamoured with either an AFX 1965 Mustang or the Ford Skairlane. Kind of leaning toward the Skairlane gasser. They have a certain mystery about them. Either way, the car will be infused with pieces of the Roswell crash. Maybe a forged crankshaft from the ship which allows its driver to never age. Like the Doran Gray of drag cars though with a more "plausible" explanation of alien technology as opposed to a painting that randomly changes without explanation. But sometimes not having to explain is better to leave it up to the reader's imagination.
