Yea, I've noticed other countries get all the diesel vehicles. Ford makes a diesel version of the Ranger pickup, Jeep makes a diesel Wrangler, ect.
As to the diesel, we have started getting the good stuff. In the United States there are now two types of diesel for sale at the pumps, LSD (Low Sulfur Diesel) and ULSD (Ultra Low Sulfur Diesel). Soon you will only be able to buy the ULSD variety. ULSD is the equivalent to the Euro spec stuff.
Now, our diesel emissions standards are going to be getting tougher. In 2007 diesels will require an EGR setup and catalytic converters, even on the big rigs. I believe after 2007 we will see more diesels as the new restrictions will be put into effect. I think a lot of companies have been waiting until they go into effect to release their new diesel vehicles. I know Jeep has been waiting to bring out their Grand Cherokee 3.0L Diesel (the engine is a Mercedes designed 50 state legal bluetec diesel).
