Well, I don't know if I'd say "offensive".....
.... but I know what you mean. I think the red interior in this loaner is nice just from the novelty standpoint, but I certainly don't think I'd fork over cash for it on a permanent basis.
The loaner, by the way, is a 325Xi Wagon. I'd never even looked inside one of the wagons before. Although it screams "Baby On Board," the extra cargo room IS impressive. Another pleasant surprise.
