If decent means can go over anything - Range Rover or Land Rover
Love the Disco 4, and my favourite go over anything vehicle (G Wagen) is available in RHD again, but fuel consumption is just absurd.
Performance - Subaru or Mitsubishi do good cheap powerful cars (see my sig for my favourite)
Never liked Mitsu's (apart from my L200) both the Forester and Outback have a hump in the middle as well as being hugely ugly, and not in the way that my G Wagen used to be. I'd possibly go for a Golf R20 if it wasn't so much money for a 4 cylinder hatchback (no idea what the back seats like).
Luxury - dunno, don't do luxury cars :-)
I guess I'm looking at a "luxury" car, but preferably A4/3 series sized, wouldn't mind going up a size if it had 5 proper seats in the back.
Guess I could sell one of the kids...
