Nice, one thing I'd suggest would be using older american language as well as using CUI instead of liters, other than that it is quite good.
Wouldn't there be some sort of coloring? Sepia would be a good choice, and there are other 50s car commercials with different kinds of coloring. I get some commercials are in black and white though, but colored commercials did exist, even if it's not as colored as nowadays. Other than that, it's pretty good for a fictional commercial.
