She Who Must Be Obeyed (SHMBO) would aim for the cheaper model. On paper it looks interesting, and even the reviews aim for more spirited driving. I do have a mountain range to climb and go back down for work, and the turbo 4 is apparently good on twisty roads. I can't spend that kind of money, and always wonder if.....
The 5l V8 is the only model I would consider for this car.
Cheers,
