I had it all to do over again and I bought another M5
but I was a little dissapointed with the braking feel and steering feel/weghting. I can now accept the steering feel/weighting as a trade off to the need for a recirc ball system. I cannot really understand why the stock car has a comparatively to the M3 and Z8, mushy pedal feel. but the brakes work great- its just a little bit in the feel, and compared to other cars it is very good.
I say "was" because I think overall the car is so good I simply look beyond these things- they are not major- the steering and braking are very good, just not supergood as I would have wished for.
