I would be curious to know how much harsher the ride is on the X4Mcomp, compared to the regular X4M, compared to the X4 M40i. Anyone test drive all three?I like the slightly more powerful engine, but don't want the bone-jarring suspension that comes with it. And $7,000 for essentially 30 more horsepower is beyond ridiculous! That is price-gouging at its worst! The performance is virtually the same for both vehicles. Save $7,000 and get the X4M.
