Re: Xr8 Or Not????
They cost a lot more to mod than the six!
They're a pretty reliable unit, you don't have to worry about head gaskets and crap like that. They're a bit thirstier around town than the six, but on the highway they're the same. Some people claim they get more k's out of the eight when doing highway kms or towing.
I think your main concerns would be non-engine related if looking at an XR8. Things like the transmission, suspension, steering, cooling system, etc, the same as if you're looking for another six.
With 4.11s, a modified engine, semi-auto, and mixed driving (heavy foot and >5000rpm often seen) I regularly see 450kms to a tank.
