My 2 cents. The V8 is excellent. I have had issues with coils packs and changed these and the plugs. The cooling system bleeder tee (under the engine cover) gets brittle and should be replaced with the coolant when you buy it (not the 10 years BS that LR advise.
I have done my own services and fluid changes etc, all bits are available and cheap. (Thank you Repco for your 25% off weekends) I change oil and filters at 10k.
The V8 does not require timing belt changes like the V6 petrol and diesel (a nice saving). I average 13.2lt /100km and have achieved 10.8 when hyper-miling.
There seems to be no down side except mine is too nice to bash down crap roads (yes, I got precious after purchase)
