GM's death list axes gas guzzlers, but which models get to live?

You don't need to be a market analyst or have a Ph.D. in economics to understand that GM could benefit from axing its gas guzzlers. However, finding the right models to put on the death list isn't an easy task. There is speculation that GM's compact pick-ups, the Chevrolet Colorado/GMC Canyon, will be included, as well as the Cadillac DTS and XLR and several other models. Buick's Luzerne could also be eliminated, as it shares its platform with the Caddy DTS, but Buick could get a full-sized, rear-drive sedan from GM's Holden subsidiary in Australia. Pontiac become be a "specialty/niche brand with reduced product offerings," according to Automotive News (subs. req'd), so the G6 and the Pontiac Solstice are set for the bin. The G8 and the Vibe might survive, though. Confirmed victims are the Chevy TrailBlazer and Uplander. Saab and Hummer are on sale, and Saturn might be phased out as well. What models would you elimiate from GM's lineup? Besides the Cruze and the Volt, which models would be interesting to keep?
