So what does the SV mean? Is this is a special car, like the ferrari challenge stradale? or is this how all new murcielagos will be produced. can you get a roadster SV, for example? Or is this make for mostly for the track?

SV is a rear wheel drive only.
My guess is that the newer Murcie will be available as an 4WD (VT), or as SV optional.
I wonder how big will the Ceramic brakes be... Maybe they should offer an option for 19'' wheels to be able to fit brakes the size of the Enzo, anything less just wouldn't be right.

im new to the lambo stuff and i cant wait for that car to come through here. those pics are great

i think they will give the 19" as serie rims, as they do with the gallardo

Really, that sounds fair to me... I guess that means even less need for aftermarket wheels(and that's a good thing in almost all cases).
