Just purchased a used 2011 G37S. Worked with a fantastic sales and finance staff - Todd, Lee, Courtney, Sarah. I presented them with tough expectations on my part and they never flinched and worked hard to make sure that I was satisfied.
Each person was fast and worked efficiently. Even when a kink came up in the deal (not their fault) they didn't hesitate to help out redo all of the work that they had done to get me into this car.
I was impressed and happy that they were transparent with the financing, showing the trade-in value, the purchase price of the car I wanted, the interest and financing terms, etc. Too often a dealer only asks "How much can you pay each month?" and hides the real numbers too the end, padding in a luxurious (and deceitful) profit. Infintii of Scottsdale had an open and honest sales process with me.
I went to this dealership because of the good experiences that my friends have had over the years with this staff.
