Try and get at least a 115PS one with a 6speed gearbox
Nice and smooth, well geared for economy and quieter gearbox compared to the 5 speed
If you like your toys, a Trend with air con. or a Limited one would suit
The traffic/vivaro range are wafer thin and the gearboxes are made of chocolate
The transporters are still uncomfortable and feel old fashioned (well it is an old design with many face lifts)
The late ones look a lot better and smarter but don't seem to have much room under the bonnet should it need anything and won't go too rusty
(but you'll be paying a lot more for that privilege)
