I have always wondered what the numbers were, and heard nothing definite. That article gives U.S production numbers as: '04 = 2432 ; '05 = 4048 ; and '06 as 1162 for a total of 7642 vehicles. 10% of these numbers sounds reasonable.
The 2004 numbers of 25XX and 2005 of 35XX were known. I just can't remember the exact numbers. The 2006 and 2007 numbers were never pinned down. Interesting that 2006 would be as low as 1500. I'll bet 2007 were fewer still. Certainly under 10,000, probably down around 8000 to 8500. I find that many here in Canada were brought in from the US. ie mine and 4doorGTZ.
All we have to do is hang on to them for 10 years. They are so rare almost no one knows about them now.
