Sure, assuming all your driving is at 70 mph, that is fine. Alas, this is rarely the case.
Quite. That does indeed appear to be the case, hence many of the replies are laced with thinly veiled insults.
No, not at all. I'm not always on the wrong side of the road, because I drive a nice V8 P38 that lets me past anything I'm overtaking quickly enough.
My other car is actually a BMW just now, although I do like Audi's, and have owned many.
My other car is a diesel, so I'm not adverse to the dirty fuel at all. But I fail to see it as arrogant to claim that 137 BHP in a truck weighing over two tons is slow. It is simply an opinion, based on experience.
As I've said before, the Range Rover is meant to be a luxury product, and with that, IMO, there should be less frustration when driving it, and it should be smooth. I mean, as I said before, there aren't too many "luxury" motors out there that don't have a decent turn of speed about them. I'm not saying all diesels Range Rovers are too slow, but the P38 is, in my opinion.
This pretty much sums it up though. If you are worried about running costs, a Range Rover probably isn't right for you anyway, but if that's what you want, then the diesel is probably the correct choice. If I wanted a reliable, cheap to run 4x4, the P38 would have been right near the bottom of the list. But you don't buy a P38 for cheap motoring. And the difference in fuel costs is probably not the greatest cost in running one of these trucks anyway (It's only around £500 a year difference, based on 8k per annum at today's prices, with a petrol averaging 20 mpg, as my 4.6 did, and the diesel averaging 28, as I'd expect it not to do much better).
I personally care not for getting maximum fuel economy out my P38, as I bought it with open eyes. I do care about how it drives on the road though.
