Yea emissions is always something that I personally would be concerned about. I would imagine that he would not change anything in that area since it would be under warranty. I kinda pushed him into thinking about the Ford with the ecoboost but no luck there. I have read about the oil bath belt and I know he isn’t concerned about that...as far as Nissan that’s a no go..so I guess it’s the GM 3.0:so far... I must admit, I’m curious as well since I would consider one myself in the future. Hopefully someone puts some miles on one and chimes in.. thanks a lot so far guys.
