There were only a limited number of the '05 and '06 models imported and some now consider them a collectors item. I would have preferred to have an '06 as it suits my needs a little better. (it's shorter) But way too big a premium to pay to get one. I like my '09 anyway. ;-)
Also remember, more people have there hand in the pot too. Someone has to buy it in Europe, someone imports it into the US, someone converts it to us specs, and some dealer sells it. Lots of hands!
