Not for me:
19" Wheels. Impractical. Ruin the ride. Expensive on tyres. Very difficult to fix. Impossible to get Wheel Insurance. A definite No no
Must say I'm a bit puzzled with this comment. Impractical, why? Having drove in 18s previously to the 19s I don't notice any difference, the suspension tends to make the difference IMO. Expensive on tyres, marginally, lets be honest if we're buying brand new BMW's I think the marginal increase is pretty insignificant really!
Personably I love the look of them and I feel they make the car!!!
