A World Touring Car Championship winner wouldn't use just any machine. WTCC champ Andy Priaulx won two of his three consecutive World Championships in the 320Si, and it is among the most successful vehicles on the series. Modified from the standard 320i, high performance is second nature, as millions of drivers have discovered since its mid-2000s release. A list of parts specially made for this machine can be found on the page that follows, and be sure to take a good, long look. A vehicle this powerful deserves nothing but the best.
