BMW X5 best road manners as sporting drive. Off road ability limited.
This made me chuckle.
BtG, we have to get you up to Rockingham to do an off-road day in an X5. I did this a few years back (previous model X5) and all attendees were amazed at how good the X5 was off-road. After the first hour we wouldn't believe we were on road tyres until the instructor let us get out and check - it really was that impressive.
RR proper - having owned a TDV8, I can honestly say I wouldn't own one out of warranty unless you are able, willing and prepared to pay some possibly exorbitant bills.
X5 - have had 2 one was brilliant (zero issues), the other had a fault and I forced BMW to take it back. Not a comment on the overall quality of the car because it was an electronic fault that no one seemed to be able to get to bottom of and one I have never heard of again within the enthusiasts community.
As a cheap carry-all and do-all, the Jeep Grand Cherokee is a good option. Built for comfort, not speed, they come with all the toys and modern ones are excellent second hand buys as well as being reliable (well more reliable than the RRS or RR-proper).
Lastly, the Toyota Land Cruiser Amazon - almost bullet proof, big and a little nasty inside (fake wood); however, the true choice of the non-poser (never owned one - because I'm too much of a poser
- but we've had 4 in the company fleet and they have all been superb (one had an issue with the air suspension after 2-years but Toyota service is second to none and it was fixed in no time).
Those would be my comments.
As for the AMV8 - can't, I'm afraid, get excited about that. Possibly one of the more disappointing drives I've had in a 'sports car' and felt engineered down to keep it away from the DB9.
