Im looking to get a new vehicle here in the next few months. I've been seeing all the commercials advertising around $4,000 in rebates on 2011 GM's. I also know they offer 0% interest for 60 months, but I dont believe they offer both at the same time correct? I also get a GM supplier discount from my employer, so it ends up being a pretty healthy discount off MSRP. Does anybody have any insight on what interest rates they typically charge if you take the cash offer?
