I've rented two of these now. Both in California, but the first one had AZ tags. Welcome replacement to the G37, which I also enjoyed, but found the interior to be dated.
It's a little low on the technology since it's a base model. The engine doesn't sound great, but it drives great. I didn't bother testing the back seat. I did turn off the stability control and found it goes very sideways if you want it too.
I swapped a 300C for one of these on Thursday and boy was I happy once I was driving. What this says is this is a very dynamic and fun to drive car, at least for a rental at $300 a week or $60 a day all in.
