Vauxhall Vivaro Van

The worst build quality! Have had the van 3 months now and I have only driven it a few times. The van has so many issues. The most annoying being the fact that it wont start, and the Vauxhall dealer ( Marshalls Knebworth ) are useless! They can't find the issue. I was told to come pick it up as they had apparently sorted the issue. Well HAHAHA it broke down a hour later with the same original fault.The fault being it won't blady start. Also the wing mirrors and door handles fall off.
