Glad you added "This year."
You're right, the 3.7 is a very different animal from the 3.0. I expected to feel at home in the new Mog, having covered about 30,000 miles in the last one, but I'm still getting used to this one ( well, that's my excuse for driving it at every opportunity!)
Too early to really compare engines. The 3.0 only really gave full power after about 10,000 miles. I do find 1st gear a bit on the low side. I think I will end up starting in second.
