Took her on a spirited drive down a twisty country road yesterday enjoying the beautiful fall weather (staying well within the break-in rpms) and I have to say I am very pleased. I honestly was expecting the 128i to be the softer, cushier sister of the 135i and while that may actually be the case, compared to what I'm used to this girl's a beast! Granted I've only driven one 135i and that was in very heavy metro traffic so I don't have a good base line to compare her to.
As for the Golf, There is absolutely no comparison. My own personal DD is a 2007 VW Gti with the DSG transmission and I thought that was 'sporty.' Psh. I'm now counting down the days to get my equity on that car leveled off so I can get my own personal 1.
