Please note I am not recommending any of these dealers, and I haven’t used any of them myself. This is simply a list for your reference.

edit: I bought a small van from Auto Capital last weekend. Their customer service was very good. So far I am very happy with the van, it seems to be in good working order apart from a bit of a leak when it rains (reading up on this it could cost a few hundred to fix…). I organised finance for it through the dealership as well.
