We've got on the mag - as a manual. It's quicker and it pulls 6th gear towing a van more easily than the 140, but unless you have a very big van, I would not worry about upgrading if it is going to be a lot of money. If the money is sensible however, it does make for a more relaxing time on the motorway.
The new PowerShift gearbox is completely new and tows brilliantly BTW. I know some owners (Surfer included?) had problems with the old, conventional autobox. There is a link to the Towcar Awards 2011 test of the car
here. The tests are completed by WhatCar?, C&CC and Practical Caravan
Any other questions, we've got it in the car park so ask away...
