330i/330ci/530i

I heard that the new 5 (E60) corners very well. Can anyone tell which should I buy for best handling &performance? 330i, 330Ci or the new E60 530i??

The 330i & Ci are lighter and should perform and handle better than the 5. So i'd definitely go for one of those two, the rest depends on whether you want a coupe or sedan; performance will be virtually identical.
