I hope that
a) it's lighter than the current 4
b) it's no bigger than the current 4
c) they don't screw up the grilles and the front end
d) they improve steering feel over the current 4
e) they don't put run flat tyres on the M Perf model
f) they offer the M Perf model in RWD
Then I might buy one
. If it's bigger and heavier, with an awful front end, I'll just have to save myself some ££ and hang onto my 440i with MPPSK
