As above don't go halfway or you will regret it again. I was in the same predicament so I upgraded from a Renault kangoo that did 35 mpg approx., due to it being constantly overloaded- to a Vauxhall vivaro 2.0 cdti which does 40mpg and that's because it can handle the weight and is probably only at half of its capability weight wise. also it only added about £50 more to my insurance, which is well worth the extra comfort and as 3 seats which helps if it is going to be your only vehicle.
Cheers all, the Vivaro does looks great but just out of my price range at the moment. £5000 absolute max, preferably £3-4K. Perhaps I'll take a look at the T4 (thanks Dskelton).
I think your all right! I probably would want a bigger van in another year :smile5:
