Hello and
The 'odd' door handles are 'design feature' of the Zed. Admittedly a bit strange, but common to all cars.
Many have made the vertical tonneau, it's easy enough to make your own with some MDF and acoustic carpet. It is/was available from Nissan, but is over £100 Check out the guides section for a very informative 'how to'
(Sorry, couldn't help it)
