No IVT on 20 series. Should have everything else. 9 litre motor in 30 series v. 8.1 in 20.
You sure? Guy here had one that was a prototype. One of the first 8520's built, was a demo and he bought it and later had some troubles with it and turned out it was a prototype that was never to have been sold. It was an IVT though I'm positive cause I drove it a bit.
For what it's worth I had a 7920 with the IVT..
