Car 3: like Graham Gouldman?
Like Mr. Goldman, the builder/owner's first and last name begin with the same letter. And it's not "G", so no points today.
Car 8: Some guy named Howard, Sanders, if not Sinatra?
No, this guy's moniker is similar to one seen here almost every day.
Car 10: Buick nailhead engine?
No Buick, but definitely not the engine this car was born with.
