I'm looking for a workhorse, that poster was looking for a fun car.
And more to the point v8 X5s cost twice what the diesels cost, trust me I'd buy a v8 tomorrow if I could get one for under 5k
The v8 645s are the cheapest of the 6 series to buy and ate comparable to the 630is, I never compared them to any diesels
@Lights thanks for the response, that's better mpg than I get in my e92 325!! To be fair I'm used to paying for tyres and suspension parts are pricey for most modern Beemers it's really the engine & box I'm concerned about throwing up massive bills on cheap examples.
