I believe they break the GM sales as separate from GMC and Chevy models........and it's a sham. If they combined the Silverado and GMC pick up sales it would put a hurt on the F-150 being the the far and away sales leader. But then again GM does NOT want people thinking they are the same truck and it shocks Me how many guys argue when you tell them they are! The Tahoe just got a ''stripper'' model to push the price down and may benefit in sales from it. They have been way over-priced IMO for years though I like them. I hope Toyota don't screw the 6th Gen up chasing what the public ''thinks'' it wants. Give us what Toyota owners want....and if that's just a update on the same platform with a better trans and a little better mileage from a tweaked 4 liter along with a light sheetmetal change I am fine.:snacker:
