Electronic central module failed in the first year.
Suspension.
Leaking roof.
Unable to load over 500 kilograms.
If you buy a Vito instead, you get the same car for half the money. Only difference: seats do not weigh over 245 kilograms, so you will actually be able to seat seven persons inside!
Don't buy a vito either, it has the same control module, mine failed twice, my roof leaks too!
