I've been with Flux a couple of times not bad quotes just don't try and move your policy or they will screw you royally with charges.
My mate also had a hard time getting them to insure him on a hire car (which they were not even paying for)
Me (25) and the Mrs (23) are with Priviledge for £420 on a 2001 IS200, Flux wanted an extra £150 on top of the modded Saxo VTS I was paying £500 for :tsktsk:
