We moved here for work (one of only has the work... not me!

Like idiots, we shipped out 2012 Kia Sedona van to Finland, and then paid 5000 euro tax... total shock. We had also paid 1800 to ship it to Finland.
The thing is, it is in great condition. And we are under the impression that we cannot even sell the van here unless the vehicle had been here for three years. We think we would have to just donate the car and not get anything for it!
So we are in a position (we think, please tell me if you know something different--)--we believe the best idea is to pay to ship it back to the states. It only has about 130k kilometers. We don't think we can get this good of a vehicle for the same price of shipping back.
Do you know something of this type of situation? The vehicle meets U.S. regulations, so it is not like shipping a car back that we bought in the Europe... we bought it in California, which has strict environmental regulations. We have the original bill of sale.
We are looking for recommendations for auto shippers from Finland to Oregon or Seattle who are reasonably priced.
Also for any advice regarding this situation. Is it true we cannot sell the van here? Are there any issues returning a vehicle to the states that was originally purchased in the states?
Thanks!
