It's not hard to essentially turn yours into an "is" if you want. Someone on here is actually selling their 313 rims and tires and I think those and the PE are the main things people love. You might just save your money then and not get the PPK or just get it later on down the road perhaps, especially if they offer a similar M Performance PPK as they just did for the F30 335i that also comes with fancy engine covers and stuff.
