Congrats on the new ride! It looks great. There are several installs done on that body style BMW here on the boards. In fact, there is a link somewhere on this board for someone who makes a dash piece that replaces the radio and will allow the 7" Lilliput to be flush mounted in your BMW - the custom dash piece looks so good you would think it was factory. To achieve this, you would remove your radio & A/C controls. The A/C would than be moved down to the empty pocket - reference the factory Navigation installation. The factory Nav install is exactly like the install I am talking about except you will have a custom dash piece instead of the Nav that matches the rest of your dash with a Lilliput behind it.
Out of curiosity - how much did you pay for it? What was the negotiated selling price (please list all options/extended warranties if possible)? Did the car have any miles (i.e. was it a demo)?
I'd love to know how the Arizona market is compared to the LA market for BMW's.
