You should be able to buy that for around 51,500 or so. If you have GMID you would be able to buy it for 51100.25, GMS would be 48666.15. Remember though that GMID and GMS are supported from the factory that is why they can sell them cheaper. On all three of those prices they make the most on the GMS and then the GMID and then the 51,500 number.
