I've only got about 210 miles on mine since Thursday (my commute is 15 miles a day) - so Sunday has been the only day I've been able to take her out on the highways.
I love it.
So far the cons:
* The gas tank "wonkiness" on MPG and DTE but someone explained/theorized as to why and that it levels out with each passing tank.
* DEF gauge -the 0% on remote start is a petty complaint. But I am waiting for the DEF to drop below 100%
* A little lag when running music from my Ipad - petty complaint
* ECO - but I've learned it and turn it off if I feel the need for more spirited driving
Fit and finish
I love driving it. I like the diesel sound without it being that diesel sound.
I like the stock 18's more than I thought I would (not the tires)
As I mentioned, I've not had a lot of time to play with every single thing. So I am still getting use to it all.
I'm coming from a modified G35 so I'm having to learn how to deal with a different suspension as to not crash.
