Your Chevy website calculator will probably agree with the Kelly Blue Book value: http://www.kbb.com/

Look up the new car you want too; it will tell you what the dealer paid for it too.

Watch the "deals" -- the more cars a dealership buys they get a "bulk" deal just like you would at Sams Club :-) If you go to a huge dealership, because they buy more cars from the manufacturer they can sell them for a bit less than the others so they can cut into their "hidden" profit more. If you take the 0% option, they're likely to bend less so the car will actually cost more so they don't lose anything. No "deal" is offered to help you; it's ALWAYS to help the dealership, whether to get people in thinking they're getting something for nothing (0%) or whatever. I would try to do like Sky says and pay for the car. The "gimmick" is if I went in willing to pay 6% on a 23,000 list price car and you insist on a 0% loan I could get the car for $19,000 (plus the loan interest) or something and you'd get it for $21,000 or whatever the difference in the interest payments would be. So, read the Kelly to find out better what they pay, what the "dealer" cost is (which is only on that one car so they'll happily show you their invoice even, lots of dealerships do that too, but the "bulk" buying gets them an even greater discount and that amount isn't available to know because one doesn't know what deal they have with Chevy/how many they bought at once, etc.) and make sure they know you know it.

The Chevy site is always going to be higher than any dealership you go to, the dealership wasn't to be THE dealer in your area to sell you that Chevy so they have additional competition with other dealers for you whereas Chevy doesn't. So, shop dealers too; you might get a better deal with a larger dealer but worry about their repair shop and service, etc. as it sucks to get a good price but then have a really crummy service department, been there, done that. The larger, cut-throat dealers often have the worst service departments because they don't pay their mechanics well, have younger/less experienced (cheaper) mechanics, lots of turnover, etc. So put all the "hidden" costs in your decision to get the best mix for you.
