Earning Some Money From A Spare Car

[lost in espace]

My son has bought a new car and I have his VW Up here at home, I only work Sundays at the moment and I am wondering if there is a route to earn some extra money with Just Eat, Morrisons et al in my spare time.

The Up seems to be a good car for this, anyone point me in the right direction for getting started?

I can buy a bolt on product from Zepp just for the hours I need.
