I just hit 2000 miles today in our 2013 X1 28 sdrive. I think it is a great vehicle and this is my 14th BMW. The only downsides compared to the 328 would be back seat leg room, gas mileage ( but I got 30.9 on a 380 mile trip today) andmslightly slower but pretty darn fast for a SUV. More utility than the 328 and better steering (hydraulic) if you get an Xdrive.
