I drove mine home on a 7 hour trip, and found it to be quite comfortable. I was probably doing 60-70 most of the time, due to a lot of it being non-highway driving through central PA.
Nissan I believe DOES have a dealership-installed cooler option now. The C&D thing was old and at that time they didn't, however it looks like they finally developed and are selling one. Someone may need to check me on that, though.
Mileage on rotary's has always been terrible. Neat concept, horrible delivery in the end
. I was able to get 30ish MPG on my trip btw, and I wasnt being 100% gentle either. I have no doubt it'd do better if I was.
BTW, what are your goals? Nice cruiser? Or eventually just going for gobs of power? 370 will DEFINITELY depreciate better than the Camaro, thats for sure.
