Whats wrong with a regular 335i? There's no performance upgardes on the M Sport.
However if you're comparing looks, then you're right. The M Sport Package looks very good and is comparable to the S4.
I had a short race with an S4 a few days back. I was quite shocked at how slow the S4 took off as I was away in a flash...However we all know the S4 has around 330HP, which is supposed to make it faster than the 335i...
