Every report I've read so far says the estate doesn't have the feel or the handling of the saloon. If this is your "main car" then yeah, it's worth the compromise but lots of people have a 4x4 or an MPV in the family too for kiddies and whatnot so it's saloon all the way in that case
Part of my wishes I'd ordered an F31 then we could bin the wife's MPV and get a sports car but then I remember I've got an F30 coming next week and let a bit more wee out again
