I picked up an SL on Wednesday from Tynan's after an abysmal experience with Autonation on Arapahoe. Tynan's was awesome, and though my car had come via a MN dealer they made sure that everything was right for me by getting some missing parts within 2 days (It was missing the SD card and cargo cover). Totally painless experience and all the employees were incredibly nice. If you're holding out for a 2018 now that the Xcel incentive is over, keep them on your radar. If they have any 2017's left I wouldn't be surprised to see similar dealer incentives coming along soon.
The Xcel incentive and a car with a great trade-in value made this an awesome deal. I'm guessing most metro area Nissan dealers did good volume in June. The stories from both dealers I dealt with were insane about how many LEAF's were being moved.
If you end looking at Tynan's I dealt with Yasha.
