I know what car I CAN'T buy, even though I would love to....a new Ford Focus wagon. They aren't making them any more!(sob!)
I'm currently driving my second Focus wagon, and it suits me SO well. Plenty of cargo space for my whole art fair setup and very economical to drive. I just came back from a 1100+ mile roundtrip to the East coast and got better than 36 MPG on the highway.
Now I'm shopping for something similar, and there just isn't. It looks like I will be keeping this Focus far longer than I had planned.
