Nice van, have an 07 2900 LWB with 2 man setup and 600 ltr tank.
Be aware of the design fault on models from June 06 to sept 09 on vivaro - traffic - and primaster which affects approx 1/3 built in this period, where water drips into the engine bay and down onto the injectors causing them to fail and also seize into the head, they are almost I possible to get out, vauxhall quoted £1295 + vat to change the injectors (4) BUT told me its a dead cert the head will get damaged so that would be another £1500 + vat.
Found a specialist, took 8 days to pull out injectors and replace £1500 + vat
I was going to sell van as we have re organised our biz, but now will run this van into the ground.
Before buying any vivaro traffic primaster, check to see if there is corrosion on the injectors, or they been replaced if not I wouldn't touch it with a brodex pole. FSH on these mean nothing as I found out !! Mine had full vauxhall history ( Anglian water ) and 107k on the clock lovely in and out, but with the injectors failing it was a bad, bad buy
