El Duderino - so you were disappointed that you drove a D3 and it behaved like an on-road vehicle - rather than a back-jarring, teeth-filling rattling, oversprung/underdamped purpose-built off-road car.
When you get drive it over some harsh terrain - you will get the same feeling. It makes hard tracks feel like dirt roads. :D
One data point on the ride quality - my father has had lots of operations on his back, including fusing vertebrae with screws and bone grafts, and none of them have fixed it. He can't drive very far in his AU Falcon wagon without suffering in bed for a few days afterwards. I have driven him down from Kiama to Adaminaby a few times - and he gets out of the D3 as if he had just driven to the local shops!
I have had more than my fair share of problems with the D3 - but still, I love it!
Cheers,
Rob
