its possible i suppose but naughty.. if you love your wheels and want a pay out if the worst happens i wouldn't want to insure it this way.. depends what car it is i suppose, if your 71yr old mother has a rs500 and your the named driver at 26 it looks obvious whats going on but i bet the insurer thinks fuck em, we ain't paying out so we ain't lost nowt.
Having said this i'm 36 and the misses 42, when i was 26 she insured my cars as it was cheaper, they where registered in her name though. nowadays it makes no difference.
