IIRC, wasn't the es model the one with the torque monster, great fuel mileage car?

The only *really good* GS BMW is the one year old E30 318is coupe. Russel Blume took 3rd in one in 2002 I think, and then went to STX with it, I think. Heyward Wagner now has one, with the possible intentions of building it for DSP.
