good question! that ST looks fantastic IMO! Electric Orange ones are a limited edition too! keep it, its a much more special and sporting car than a 3 series!
Made me laugh when Tiff had one of these to play with at the Rs owners day At Combe a couple of years back, came into the pits and asked for some pliers to disable the electronic aids!!!!
But yeah, Orange looks great, Every Marshal should be issued with one!
