I drove several different 370 models (all in 6MT because that is what I really wanted) but never purchased because of the traffic conditions in my area. The day I decided to test drive an auto I wound up signing the papers the same day and took her home. But like everyone has said, drive one. Only way to believe.
But if you are looking for the same performance of a subaru you would certainly need to stick to AWD. Why not just get a GTR? They're ALL auto!
And all the people who would essentially make fun of anyone for driving an auto all seem to shut the hell up the second a GTR rolls in. Soooooo....
Good luck!
