There are still 2006 and earlier U500s for sale and allegedly they brought quite a few in prior to 2007. 2007-2009 models will not be imported due to 2007 EPA emissions but when Euro 5 comes into effect in 2010 they will start bringing them in again, Since Euro 5 exceeeds 2010 EPA. But, as mentioned, new or near new U500s can be found and the earlier ones are (relatively) cheap. $70-80K is a great price for an almost new U500. None of the 4 on Ebay had CTIS; only one had the electro-automatic shifting (which works great on mine). Those two options are worth about $11K. All had working gears (5.77 low range) and one had the heated windshield, all have at least basic hydraulics. The cheapest one is just a cab-chassis, the aluminum bed is pretty expensive and of course un-necessary to build a camper.
