Not all car makers in auto script

[AutoTrader]

I've just noticed that there are Car makers missing from the auto script.
One of the reason I bought it was cause I thought that at least would not be one of my worries.
For instance SEAT and OPEL are not listed and of course their models... am I doing something wrong or is this the case?

I think I found the problem... the car makers are not in the translations...!!! So... I'll have to do almost all models manually...!!!

Revisiting this a year later, have you added all the car makers / models in the translations?
I've just downloaded the English language and almost all Car makers / models are listed as N/A
