I'm at 25 mpg.
Why X1? It has turned out to be the perfect choice for me. The size is great. Skis stuff, no problem. Bike, no problem. This weekend we were four people driving to the mountains with all our ski gear with no issues (thanks to the middle seat fold down).
The drive and handling are great. It's so much fun to drive. The basic sound system works great for me. over 250 songs on a small USB stick categorized into folders for easy navigation.
There are a few quarks, but none are show stoppers. The auto/start/stop is annoying and the shifting up and down is counter intuitive (up is down shifting). But both are small issues (the first one can be turned off by default by the dealer).
I have about 5k miles and I'm really enjoying the vehicle.
