HOTSRT8
The Chrysler 300 may be the best modern sleeper car; when equipped with the SRT8 package, and a non-vanity license plate to let people know you have a SRT8. Most likely this owner thinks making the car identify as being self aware is ironic.
However in another dimension this person could be advertising that they are driving a hot as in it may be a stolen SRT-8 or maybe they felt like they got a really good deal on the car (which would never happen on a relatively rare 300 SRT8).
Are you looking for inspiration for your very own personalized vanity license plate we have tons of muscle car vanity license plates here and you can see what the drivers of Mustangs, Camaros, and Challengers among other muscle cars are up too.
