What you think of the Z4 M?

Was racing against one three weeks ago on our national track
was very fast but still look bug ugly!
also M3 on track at same time, seems amazing but probably due to the fact that the driver was very good, saw the same car last weekend on wet track, was a very different story!
test drove the new M5 and this is amazing!push that booster button and waoh! it goes, but too complicated like an over programmed dishwasher, 3 set of suspension and five set of power for each setup. too much hassle!
BMWs are not bad but compare to a real racer like a 911 or a well sorted Boxster forget it.
