The 'New' Peugeot thingy that Vivaro and Citroen are in cahoots with has a good auto version........... they look smart but have less space - probably great for tiling.
i have a merc 111lwb have a rack in where i can get 20 sheets of 6 mm ply just below the roof line and above all my kit. its a 2.15 diesel and i get about 35 mpg and dose a ton with ease ,probably why only 35. like driving a car thinking of getting another for my son the 3ltr sports auto looks really good. some bargins on gumtree
if you get a transit get your looks changed as there easy to break into know several people who have had there tools taken and had to fork out a fortune to get set up again
