^^ this.
I live/work in the Surrey Hills. My route to work is up a series of narrow, winding, hilly roads - work is a large former farm house in the middle of nowhere. I remember one year (in my old D2) where I was the ONLY member of staff who managed to get in. Driving up the hill near my destination I came across a jumble of BMWs, Mercs and a white van. All of whom were stuck half-way up the hill. I stopped to help a couple of 'em out of the ditch, then got back in the car and continued cruising regally up the hill whilst the rest of 'em struggled back down in barely-controlled slides. I saw the word 'b*st**d on the lips of a guy still struggling with his 7 series..
Now I have the D3, I just leave ESP on and let the car sort it out. Just stay away from deep floods - you only have the ground clearance of a regular car and floods are bad for your 8 mmmmkay?
