Stuff all that tekkie bollix, V6's are cool as & pull like the proverbial. Keep up the oil/filter changes & change the cambelt/water pump every 40k or 4 years.
Then ENJOY!!! 8-)
reeeaaally missed my v6 today, havind to drop a couple cogs joining the motorway at 55mph in the 2.2 just feels like i have to work it soo hard!
really if i could use a 2.6 and do the trips that i mostly use mine for to see what differance in mpg i get id be happy.
i really dont want to get a v6 then find im much worse off fuel wise, but i have this feeling i wont be as im having to push the 2.2 hard.
I went from a 2.2 auto to a 3 litre manual and still got roughly 300 miles to a tank. Not sure what the 2.6 figures would be though. And it is infinately more fun to drive.

I tend to do a lot of short trips, school run etc. so economy isn't great for me. Can/could get 500 miles on long motorway runs though.

I dread the day I no longer run a V6.

I'm guessing big car means bigger engine doesn't need to work as hard as the smaller one does? :-/
