Well if fleets are about 1/3 of sales (I believe they were in the past), and 1/3 of sales were down 28%, that means that the other 2/3 of sales had to be down 10% to get an average of down 16% (10%+10%+28% = 48/3 = 16%). That's a very rough estimate, but I'm guessing that's relatively close (+/- 3%).
There was -1 Classics sold
Anyways, there were not many bright spots...
The CTS needs to get here NOW, the LaCrosse needs a refresh but the Lucerne seems to be doing well, it looks like the DTS was hit hard by the fleet reduction, and the STS needs a refresh too. The Aveo should pick back up when the new one arrives, the Cobalt seemed to do relatively well and the Impala did well. The Malibu appears to be the victim of reduced fleet sales once again. The Z06 is giving Corvette sales a boost it would seem. G6 did well, GP was down due to fleet probably, and the Solstice continues it's torrid pace. The Vibe needs a redesign. Saab continues to suck, and the SKY helped Saturn out quite a bit.
Buick really needs the Enclave ASAP, the Escalade is doing well and the SRX was up surprisingly. I'm surprised the Suburban is already at near year-ago levels, but everything besides the HHR and T900s sucked for Chevy trucks. Same thing goes for GMC. The H3 has really taken off for Hummer it would appear, and the Torrent is giving Pontiac some much-needed volume.
All in all, a terrible month for GM. Very few bright spots. Until the Aura, new Malibu and CTS, Lambdas, a T900 pickups come I'm not that optimistic that GM will do very well in sales.
