Got it on our TT.
I like it, it's pretty cool ... but it was free on the TT.
Price point would be a big thing for me if it was an optional extra, although what is the cost on an A4 as guess it will be similar to that. That said, on the A4 don't you have to spec the high tech pack in order to get the virtual cockpit ?
So if that applies to the 3 range then it could be a £grand for tech pack then another £600-£700 for the virtual dash perhaps.
Fine if you want the tech pack but if not it could be expensive if Audi force you that route to get the virtual dash.
But Audi are masters of the optional extras lol ££££££'s
