The crossover market is so crowded at the moment that car maker use every edge they can get over the rivals. Chrysler, for example, hooked up with the Rolling Stones in a charity effort to promote their Jeep Renegade while helping a good cause.

Jeep is was fact the exclusive automotive partner of the Rolling Stones’ “14 On Fire”, yet another farewell tour that didn’t stick! The Jeep Renegade in question here was present at the band’s Rome gig in June, where it was signed by Mick Jagger, Keith Richards, Ronnie Wood and Charlie Watts. The vehicle is now up for auction and all the proceeds from its sale will go to nonprofit organizations around the globe. Current bid at the time of this writing stands at $42,500.

Jeep Renegade is the first model in the American brand’s history to be built in Italy and the first Fiat Chrysler Automobiles vehicle to emerge from the collaboration of Italian and US designers. You will find an awful lot of Fiat stuff underneath the body, but it is still a true Jeep at heart, boasting features like 9-speed automatic transmission, two drive systems, rear axle disconnection device and an instrument panel complete with 7″ display.
