I have found on autotrader.com some of the cars have the MSRP listed and the info is provided by edmunds. They don't have it for every car and the car has to be for sale on autotrader to get to the link. I haven't been able to find the info on edmunds.com though.

I want to know this because where I work they are changing the auto reimbursment program to some awful plan run by Runzheimer and I need to get a different car.
