I need to determine the dealership and equivalent retail sales for new
'sports utility vehicles' in the U.S. during 2003.

Your question is a bit broad to be asnwered exactly. What is and what
is not an SUV is particularly difficult. So called "crossover"
vehicles such as the PT cruiser or Rav4 which look like trucks but are
on car platforms muddy the numbers either way you count them. You
almost have to have a guide for al 183 models to determine one
classification set. That said the data below comes from a name you
would recognize and is used by many industry experts.  Further I am
fairy comfident in both the direction of change and its relative
magnitude, if not the absolute level.

1985: 771,458
1986: 822,617
1987: 905,256
1988: 960,852
1989: 944,243 
1990: 929,066 
1991: 909,577 
1992: 1,133,137 
1993: 1,379,806 	
1994: 1,556,075 
1995: 1,753,404 	
1996: 2,140,455 	
1997: 2,435,301
1998: 2,794,207 
1999: 3,218,301
2000: 3,511,652 
2001: 3,933,357
2002: 4,186,260
2003: 4,511,199

The unit volume you have listed is close to the information I already
have from the Automotive News 2004 Market Data Book (4,445,437 units
in 2003). What I need are retail equivalent dollar sales for the unit
volume.
