I'd have exactly zero interest in one of those. With my nephew's kids living next door, the 2004 we have now goes plenty fast enough. But then I don't have much use for the fancy aluminum wheels and cabs either. Ours gets used every day, at least twice a day at chore time with an open cab and a roof onto to keep the rain off, sort of. It spends it's life covered in mud hauling a dump bed full of horse manure every morning, feed and hay at other times.
We look at it as a rugged tool. I like the fact that it has a three speed transmission. We use the M speed a lot crawling around in the mud in the barnyard in the spring. L is too slow, H doesn't have the 'stuff' to move it handily in the mud.
Maybe if I used it to plow, I'd want a cab, but the skid steer is a whole lot better at snow removal.
50 mph? I have a Diesel pickup truck for that.
