Thanks for your comment & thoughts, nice comparison.
Would be interesting to know what model you exactly refer to, but sounds good - Ti Sport with LSD from what you mentioned?
Doesn't the TI come with 280 horses - 306lbft (you mentioned 270 - 310)?
X5 will lose this battle, but despite that, I personally appreciate, that there is another rival for the 3-series. That will hopefully wake BMW up and keep them on their toes
