I would prefer the car to be unmarked.in this case Fall S Fest could have been shortened to; FSF 2011. Would be a reminder on where I got it, and not be so blatant.
I would accept fictional industries or roadnames if they were well done. Nothing ruins the appearance of a car worse than inappropriate fonts. Modern lettering on a steam engine, wild west lettering on a modern car. Roadnames that are puns.
