So, having read the article previously, the main points are lack of an LSD (agreed, its an omission on the RS), crashy ride (disagree, having driven both the Alpina is a better ride over uneven surfaces - 18" alloys is a small change if needed, and the suspension is more forgiving in the Alpina), and brakes (never found the Alpina brakes an issue, so would disagree with that point. Unless, of course, he'd cooked them on his test drive). Would also state that the power curve is smoother on the Alpina delivery than the ///M, which I found more brutal in its application.
But, of course, this post isn't about which is the better drive, more about which is the better investment. Alpinas have the rarity but a small market for buyers, ///Ms have the volume, but a larger potential buyers market. Neither will make you much money unless its a low mileage, immaculate model in 20 years time. And, for most of us, that's not the reason we purchased these cars.
Finally, for me owning an Alpina is more like having Raffles burgle your house, and owning an ///M has the local ASBO youth performing the same service. The end effect is the same, but the experience is vastly different.
