Running Wild Time and Time Again

One man infiltrating a racing gang would be difficult, but Ron can't resist. He's the best car racer in the Auror department no one else could keep up with infamous Harry Potter, ex-convict and suspected thief. With runes etched on his engines and spells in the petrol tank, getting the crew's attention should be easy enough. Or so Ron thinks. [Inspired by the Fast and the Furious]
