Big B5S4 fan here and own a stage 3 silver S4 but happened to be driving my E46 M3 on Interstate 10 today near Redlands California today. Came across a beautiful Nogaro Blue S4 and lets just say we had a "spirited" run. Not sure what he has done but M3 performed nicely. Curious if the owner is on Audizine. Nice run BTW if youre on here!
