Btw I also contemplated cancelling the 125i when the M135i was announced.
The comparable spec with options was still a considerable more money, plus in addition to the extra road tax and fuel bills. Additionally BMW were not offering anywhere near the same deals on finance at the time.
The running costs alone did it for me, with the mixture of driving I do it just didn't work out.
I'm sure this will be the same for others, particularly for those thaus one with company car/car allowance. So it isn't quite the no brainier that many are saying on here to automatically go towards the M135i...After all isn't this quite the same deal in regards to the GTI/R?? Might be a larger gap, but there is a prominent market for both.
