Re: New Wk2 Overland v8 or 3 year old used X5 4.8i??
WK2 for certain.
As sweet as a 4.8 X5 is, they're not a vehicle to own out of comprehensive factory warranty, and the stories are growing daily of very expensive fixes judging by some forums I've seen.
I've not driven a 5.7 WK2, but I still think the 4.8 X5 would be a better drive, but the Jeep actually has some off-road ability.
