I am in the market for a 2007 Silverado 1500 Crew Cab. The new GM pricing strategy seems to involve allowing invoice pricing, 2.9% financing for 60 mo. & $1,000 customer cash. How much is everyone paying with regards to invoice...1,000 below....maybe 2,000 below?? I want to find out what folks are paying to get the best deal. I couldn't find a pricing thread.
