Had an hour to play so I basically drove back home and along some roads where I’m familiar with the M3. Honestly the handling seems fine - its not that much taller but it is a lot more comfortable to get into so thats a tick for me. Boot is odd - its massive but the parcel shelf is horrible. Much prefer something retractable, you have to punch this from underneath to get it to fold and then it sort of flaps there. You can barely see in so maybe I’ll remove it. On my 3 I can keep my ‘usuals’ under the floor and that’d be easy in the Y even putting shopping in there probably
the lack of USS I can probably manage with but it was bonging at me all the time. I tried a reverse park and it was freaking out at a very low kerb - no lampposts or anything nearby. It was so obsessed with the kerb it seemed to ignore the car behind me getting closer as I reversed.
Main thing honestly is the motor (and range but you can’t test that on a short trip). Its still ’perky’, but not ‘pokey’ like the 3LR. I tried putting my 3 into chill mode as a test and the YRWD is better than that (chill is oddly sluggish as well as less power) but closer to chill than to the instant push back in your seat you can do with the LR on demand.
Having said that, these days with traffic (and certainly with passengers) there is precious little opportunity to do that, so I think its something I can live with. Its still probably more responsive to teh throttle than my previous 420i was and I lived with that happily for a few years.
