I agree... in the case of Lexus, the hybrids are all the most upscale of the RX, LS and GS series. It would be nonsensical to try to compare sales figures for the Lexus marque as between hybrid and conventional power trains. Would one compare sales of AMG Mercedes to conventional mercedes?

Really the comparisons are between the Saturn Green line and conventional Vues and Auras, the FHE/LHM and now Mazda Tribute hybrid, the Civic, the Camry and Highlander. The Accord doesn't count because it tried to pull a "Lexus upmarket" with it's more-powerful-than-the-conventional hybrid engine-- and honda failed miserably at that.

Then, once you've got it down to that, you can't compare the base Civic, Camry, etc., to the hybrid, you have to at least compare the LX or whatever trim has comparable features. I agree completely. But this is all too subtle an analysis for people who don't know anything about the market.
