Sorry to dig up an older thread, but a colleague of mine at work just this afternoon took delivery of his new 1 series. It's not an M135i by any means, just a "lowly" 116D M-Sport, but I have to say to being mighty impressed.
It's totally bog standard apart from the M-Sport trim level, slate grey paintwork (like the Golf TCR grey) and double clutch gearbox. For a BMW, I was very impressed at the standard level of kit. How much of this is part of the M-Sport trim, I don't know, but as standard it has very smart 18" alloy wheels, Full LED headlights and tail lights, large single chromed exhaust, leather (pleather) interior with seat squab extension, auto folding and dimming mirrors, auto lights, wipers, parking sensors, cruise control, digital dash, dual zone climate control, LED ambient lighting, leather steering wheel, Sat Nav (on what looks like a larger screen than my 8" unit in the GTI), city emergency braking and Lane keeping assist and Apple car play.
TBH, he's said the only thing it's missing coming from his MK7 Golf GT (his outgoing company car), is the adaptive cruise control, rear view camera (that his Golf had) and the load though position and rear arm rest in the seats.
For a diesel it's extremely quiet (although it has only got 56 miles on it), and the interior, rear and boot space now seems to be on a par with the MK7.
All in all, very impressed. Think the MK8 will have to be something very special to beat this (unless you are a BMW hater) ?
