I think your best bet is to wade through them via online quotes and see what each company offers. No two people get the same quote as it depends not just on your age, but licence, area you live, type of car, safety measure fitted to it etc...
Because of your age etc and depending on what car, each company is going to quote something different.
Also check what group your call falls into. You can do this online also, so you'll have an idea if its one of the cheaper ones to insure or the more expensive.
