I'd be interested in a group buy too as I've got LHD ones!! £180 is the reason I haven't replaced them! How much cheaper would they be if they came on a boat or in a group buy!? I previously paid £80 for RHD ones but got sent the wrong ones!
Surely if you put your mum/dad/gf/dog etc on your insurance and you stack, they have to also have the accident registered against them as it happened on a policy they were linked to!?
Harsh! If it makes you feel better I got my first 3 in ten years 6 months ago!
Still, in my case I can't say I haven't been lucky surviving as long as I did without them!
