I apologise for thread-jacking in advance but it's very interesting to hear that you find it more of a cruiser even though it's a 3L twin turbo, it seems all owners of big engined non M BMWs from 3s to 6s reckon their cars are more suited to cruising, the same with 645 it was exactly described as a lazy cruiser. Non M e60s have no LSDs (Non Ms in general I suppose) And even e36 328/323s have the 2.93 diff which makes for ludicrously long gears... again suited for cruising. Still though, hard to beat 50/50 weight distribution when the going gets twisty
