Yep cant go past the BMW's, Please just dont use your X5 offroad, They blow their transfer cases when they have to shift power forward. Only good for snow or really slippery conditions. How ever those straight 6 petrol's are amazing.
Haha, it was bought strictly as a motorway cruiser for the family. We are all very tall and it was the only thing we could all fit in comfortably that wasn't a people carrier/van. I've had M70's, M62's and M54's and specifically wanted the M54 for this. It's far from a screamer but it has more than enough power and in 18 months it's at 11.2l/100km. I wouldn't get near that in a V8.

I have a M52B28 in my E36 and im sitting on 200KM, The engine runs smoother and quieter than most new engines, Doesnt miss a single beat. Cant even hear it running or feel it running when its on. The other massive benefit is that my little 3 series is so damn quiet on the road compared to others.
My ancient BMW is quieter and smoother than my mums brand new Mk7 Golf.
Oh yeah the other part, its insanely reliable..
Yep, my 1990 e34 535is is at 320k and it's far smoother than the 2007 Focus we just bought.
