I didn't find that the on/off feature turned off after reaching 10 mph. Once I shut it off it was off. I think the main thing I've discovered is this vehicle is less expensive because it doesn't have all the electronic gadgets. Once those are added, it's the same price as an X3 or a 328. I started out wanting an X3 and thought the X1 would be a lower cost alternative. It really doesn't provide the SAV function I wanted. As I've gone through this process being honest with myself I really want a sports car. The SAV need was me compromising with wanting a BMW but wanting something practical. I'm still going to drive the 35 xDrive next week but I'm starting to lean toward the 335ix.
