man they both have the same gearboxes and ratios and one is quite a bit heavier,you sure you weren't
i tested the 528i up Western St............
i do respect opinions, hey this is supposed to be a forum to enjoy ourselves but if you want to say that its not underpowered no problems,great
but now you say it feels "faster" than a 328i than i dont think its to got to do with physics at all.
its just like when people compare the 335i to the 328i, of course the 335i is much faster and of course a 535i will spank the 528i, thats the truth
