Congrats. That vehicle is a weapon, and will be fantastic on and off road. The CVDs are POSSIBLY susceptible to heavily corrugated roads like the GRR, as one owner experienced. But improve the ride and handling even more, which is hard to believe.
The difference to the Defender will be huge. I went from a well sound proofed turboed Perentie wagon (still have it) to a 3.6 L322 about 3 years ago, and love it.
