you worried they might prang it or something? thats what insurance is for...
when i had no licence my mates drove my skyline, they loved it... i loved being in the passenger seat as i trusted them as a driver and your car feels much faster when your in the passenger seat
my ex drove it too, she loved it, learnt to pothole dodge, sideways driveway and burn people off lights...
ay even sammeh has driven the S4 along with a string of other people and everyone has loved it... i think i have converted him...
fair enough i wont let people drive it that i dont trust, or that will screw me if they smashed it... but everyone else can go for it...
try it linton, you might enjoy it!
