I fully understand this, if the seating position isn't for you then it's definitely not the right choice. I had an A4 S-line for 2 painful years that I had to endure and I didn't even want to drive it.
Yep I looked at an A4 before concluding I wanted a newer hot hatch instead and that seemed to have a similar issue, the clutch pedal is in a really weird place.
I get that the M135i is technically a better car than the others but a combination of the comfort issue and higher running costs (partly due to the age/mileage I'd be able to afford and partly due to it being a more complex machine) mean it doesnt really fit the bill
