I'm not even going to compare what I pay with others, as I'm an old bastard, and evryones situation is different.
But they are cheaper than Just Car, and they give you your own choice of repairer (Just Car don't). Only thing is you must park the car off the street, doesn't have to be garaged, driveway is OK.
If you have your full license they should accept you I think.
