I can say my 125d m sport has a very comfortable ride despite the run flats. I think BMW have had to look at it as it was indeed, sodding awful. Also the old 1 series was a crap car, space, ride, spec, price, it was all below par.
The new ones are better in all ways, except possibly price but as mine was bought 2nd hand with 70 miles on the clock and £8k off list it seemed bloody cheap anyway!
Would love a play in the 135 but honestly, the 225hp in that sized car along with a load of torque is as fast as il ever need.
However, at the right price and as long as work still paid all my fuel? That’d be fun…!
