Looking to purchase a new 2007 Chevy Silverado within the next month. I am refering to the new design and not the "classic". I have the MSRP and Invoice price for the LT1 extended cab which I got from Edmunds.com I am very curious if anyone has purchased one lately and what price I should expect the dealers to remain firm on. Any feedback would be greatly appreciated. I am purchasing with a one time check and don't get any "plan" price breaks. Thank you.
