2009 Suburban LT MSRP 47,830 4,000 rebate Quoted invoice and rebate at $41,730 Am I missing any available discounts? Dealer did not mention $1,000 old age discount (car has been on lot for over 45 days) and he did not mention $500 discount instead of 60 day return option. What about financing discounts? I dont have a GM card or anything like that. He showed me invoice and it was only 2,100 below MSRP. I thought invoice should be around 3-4K under MSRP for the burb. Price seems high considering it's only about 13% savings.
