I was supposed to have a test drive this weekend but had to cancel. I've got no intention (or £100k!) to buy one either but it's such an intriguing car. I've heard that the power output is one of the only issues people have, but the overall package is what makes it desirable I guess.
Nothing yet. Sold it because we're moving house and I wanted some buffer money in case we need anything doing that is outside of the budget. Hopefully it won't be and I'll buy another BMW in the summer. Not sure what I'd replace it with yet but I like the idea of a 640d. For now I've got an E46 330d touring, which is perfect for getting me to work and back and for cycling trips.
That's interesting you say the M135i feels faster than your Z4 because I thought it was the opposite. There wasn't much in it, but I thought my Z was slightly faster. Did you have the DCT gearbox in your Z4?
Yes, mine was the 35i with DCT. For me, the M135i is just so much easier to drive fast. It doesn't sound as good but the power delivery and handling is much better IMO.
Have you driven the M135 much?
