My wife and I are about to place an order for a 2008 FEH AWD fully loaded. (i.e. Hybrid Premium, Moon/Sat, NAV). MSRP is $33,565 . Because we need to preorder the car, I am not sure what negotiating power we have. What should we be paying? What have others paid on pre-orders? I noticed under one thread someone offering $500 over invoice. Where do I find Invoice info. Thanks!
