What car would suit?

Berlingo/Partner/Kangoo with Amdro Boot Jump camper kit and tailgate tent. http://www.amdro.co.uk/boot-jump-camper ... -p-52.html
Not cheap though for what is basically some plywood etc.
Two road bikes with front wheels removed fit across the middle, see 2:30 into this video https://youtu.be/ESxNPYVVbZc

Looks expensive when This guy can knock you something suitable up for £450.

Yes indeed, much cheaper, think that is the same as this one https://www.spacecampervans.com/ but not quite as elegant as the Amdro and with no cooker etc, and cushions are extra too.

I think there is one on there with cushions, pull out draw and cooker for £750

I have had a lengthy test drive in both the Partner and the C Max. I like both so my decision will be between these two. Because I have quite a lot planned over the next few weeks I shall make a final choice in October.

Thanks everyone for your suggestions, even though one left me totally confused.
