The 3.8 is much quieter, quicker, smoother, and a lot more responsive.
The drive train is the same other than the engines, and the auto trans.
The clunky manual is the same in both cars.
With the 2.0 turbo, you can spend about 4-5 grand, void the warrantee, and have "ALMOST" as much performance as the stock 6 cyl.
I drove both the 2.0T and the 3.8 with auto trans and manual before making my choice.
There was no comparison.
