I had a test drive in one, found the ride very harsh (could have been the runflats) compared to the Focus that I was replacing.
Boot is OK, similar in size to a focus.
Lacks rear legroom IMO.
The salesman I dealt with at my local main dealer was a stroker of the first order so my view of the car may have been tainted…
Overall probably OK but I think the current Focus is a nicer place to be, handles better and is significantly cheaper to buy (I didn’t buy a Focus or a 1 series).
EDIT, just noticed it’t the newer one you’re looking at, the one I drove was an 09 plate 120d
