You'll love it. The hardest part is waiting the next 7 days. I know what it is like after waiting for 5 months for my D3 then seeing it all wrapped up at the dealers - just wanted to get in it and drive it.
Make sure you visit the forum page for D3s found on this forum and also look around the forum for D3 owners
www.disco3.co.uk with all the information you ever needed to know about the D3 plus more.
