I won't re-state any of my opinions, as I'm sure they appear already in those posts, but I will add two things.
Mileage - I have now done 12k miles in my 2.7, and there is no doubt that the engine continues to get stronger and more flexible with the passing miles. This is important, cos I don't think a box fresh 2.7 gives you the full story of how good this engine really is.
Other opinion - The respected UK journalist Chris Harris bought a 2.7 and wrote several very perceptive
articles about it. I have copied them
here if you would like to have an other opinion.
