 I have had four successive 5 series wagons. Sadly, BMW doesn't bring them to the states so I had to really consider what to get next. The X1 was TINY and just didn't feel like a BMW to me. Without question my last 5 had a more luxurious interior, but that's expected. The X3 has a much nicer interior than the current 3 series. The screen is IN the dash where it should be, not sticking up like a design afterthought. The engine/transmission combo is amazing; very quick and agile. It doesn't handle like a car, but much better than other SUV's. The tech package is very nicely done. Gas mileage is really good for the size. The car feels much lighter than my 5 wagon, much faster though.
