I originally had my mind set on the iX, but the M50 variant is just crazily expensive on lease, so started looking at the i4 M50, the air spring suspension had me intrigued and it's great, very refined, loads of effortless power.. In fact the only flaw I found was the rear door openings are bizarrely small and a weird shape to a point that you have to contort yourself a bit to get in/out.. However on a test drive, I was amazed that instead of the more sporty focus I thought it would have, it was quite refined/isolated and a departure from the ICE 'M' sub variants (M440i, M240i etc).Be interesting to see how you get on, I think of the model 3 as a very fast car, but it's clearly not 'sporty' imo. I'd love to go for a taycan to solve that, but I don't have 100 grand lying around.
And to back that up.. From Car magazines i4 M50 vs M3P:
The BMW feels better built. Not a surprise. But this is a surprise: the Tesla’s more fun than the BMW. It’s not only preposterously fast in a straight line (in a way that pins you to the oddly shaped headrest) but the lack of bodyroll and the quick steering make it a laugh in corners. The i4 has better steering feel than the Model 3, keeping you more in touch with what’s going on. But it’s a shame the i4 doesn’t seem keen on you being involved. For a BMW, it’s a bit inert; safe and unspectacular.
I've driven a couple of M3Ps and whilst quick, it's actually their more hooliganistic/involving nature that I found more at odds with the EV aspect.
