strangely enough it won't cost as much to put you onthe insurance as you think, as being a learner the insurance take into account you have an experienced driver sitting by you.
I didn't know this, so never insured my car as a learner, or i didn't even think too. Lucky enough i bought the carmonday and passes on the wednesday lol.
To add you on the insurance as a named driver when you pas, will prob cost a bit more then too. Yet all the insurance companies seem to differ wildly in costs.
My dad put me on his as a learner and it didnt cost anything, which i thought was rather risky and odd.
