The first link went to a non-M Sport saloon there.
No matter, as you say looks are important, so surely the elephant in your room is saloon vs touring isn't it?
In your shoes, I think I'd plump for 318 M Sport. In fact in my shoes I'd do that. To me, a touring is bought for those rare occasions you need extra carrying capacity.
Performance difference yep of course, but less of a difference than the visual one.
