Hey, I've not got much of a clue when it comes to car insurances in the general sense with additional drivers onboard so I'll just explain my little predicament.

Me and my girlfriend are sharing our next Uni apartment this September, and in order to save money during that year we are also planning on buying a second hand car and paying 50/50 between us.

She is waiting on her test and I have yet to begin (shall begin in September).

Is it a good idea/generally more expensive to have 2 first time drivers sharing a car on the insurance? One of us would have to be main driver (probably her) and I'd be the add on additional driver.

Otherwise should I consider finding a car of my own and paying mine separately?

Thanks to whoever decides to help clear up my confusion.
