What about the Passat wagon--it's a full sized sedan/station wagon--?

The Passat TDI wagon was never sold in California due to emissions.
I could import one from another state, e.g. Oregon, provided it has
enough miles on it. VW supposedly will introduce a cleaner diesel engine
next year. But by then, the 2008 Highlander Hybrid will be out, and it
might get better mileage, especially in town.

Toyota RAV4 and Ford Escape hybrid get fairly good mileage for an SUV,
better than any minivan. After driving dirt roads with a rental minivan
last week in Idaho, I can see why boaters usually prefer an SUV.
