Here are the numbers I know from my own purchase:
The MSRP including the $900 "Inland freight and handling" is $52,300 on a GT2 AWD. The dealer invoice for that car is $49,113. A difference of $3,187 plus. That does not include any other dealer incentive or quota allowances that no one knows but which dealers get under the table. $595 for window tint is insane and is a pure profit item added to your cost. Also be aware that any "lease cash" rebate is strictly between you and Kia Corporate. The dealer may use it to advertise your net cost, but the dealer has nothing to do with it, and you do NOT want to get that signed over to the dealer to play with numbers embedded into your lease or finance payments. If you do lease or finance the car, make sure you get a complete and total accounting of each and every fee, charge and add-on that goes into making that monthly payment. Dealers can hide all kinds of things in there if you are not watching them every second, and most people are so focused on the monthly payment that they get hosed on the details. Be careful, very careful.
