Very cold day today..
I used M.Toad with tonneau cover only (To my eyes 4/4 4 seater is ugly with with side screens).
It is mostly OK with heater on...except for my right arm :-/
Having a Lotus Seven backgroung I would like to know if some of you use a half door as I do on the 7
Like this:

And if it is. Is it only a DIY job or someone manufacture it ?
