Based on specs comparison, GTI has better speed and acceleration, that's a fact. So, if we wish to have a head to head comparison I think it cannot be just based on speed criteria alone. If speed is what defines the car then sport models should be much desired purchase. Unfortunately it is not the case. When I decided on 320i, I knew that other models can run faster. Prior to that I was mulling over recond. Audi TT, Z4, etc which can also beat VW GTI if put on the track. I also considering a merc. but cancelled my booking (still trying to get my refund even after 2 months...darn). Finally I had decided on 320i. Why F30 320i? Well, you have your own good reasons why you have selected the models that you are currently having; and they are all good reasons. For me, it is partly budget, sense of value for money, brand name, latest model (not facelift), 320i perhaps has better resale value imho, etc. So if next time a VW guy or fairlady or audi r8, skyline GTR, etc. wish to race me on plus highway, I would just let them pass. I am happy to enjoy the drive and stick to 120 km/hr.
