i'm 22 and cos i've always been a second driver i had no no-claims bonuses and people were offering me rediculous things like 1500 f/c..... but i could only drive it once a month and had to get a tracker fitted (my postcode did me no favours) so i shopped about and got it on classic insurance. well'a cheap.
you'll be able to get it better than that though, try a few online quotes. i'd say around 1k probably?
