That's weird. Whenever we take in our BMW's to be serviced, they give us a very similar model to drive out. We've taken our 325Xi out, and we got a 325Xi as a courtesy car. We took the X5 out, we got a X3 as a courtesy car. Now, the X3 was a bit different but since it had the 3.0 liter engine, I wasn't complaining as it was the same engine that powered our X5. Other times, when they ran out of courtesy cars, we had to sit in an Isuzu Rodeo (What they called their limo service)....all the way back home.
