I Highly Doubt It

BMWphiles: Will The X5M And X6M Be MORE Collectible Down The Road OVER Passenger M Cars?

Will the X5M and X6M be MORE desired down the road over other M cars?

While I must admit I chastised the M sport-utility vehicles previously — before I drove them — I have learned to love these monsters. They're so incredibly capable, spacious and, in my opinion, better than the current-gen M5 sedan.
And if there's one thing that doesn't appear to be slowing down or changing, it's consumers affection for SUVs.
