Woah thats expensive! Hmm sorry to say but Quinn are probably the cheapest I'm afraid.
Can I be bold and ask what age/s3x, NCD/Driving experience you have? If you're young like I think you are you might be limited to Quinn or Britton Insurance (

Hibernian may take you on if you sit and pass the Ignition test, but they will probably consider your car a "performance" vehicle and not quote you at all if you have MIVEC. I know from experience a MK1 MR2 (1.6) is considered a performance vehicle.
Well done though! Thats a huge lowering of your premium! More money for mods
EDIT: Ha why does s.e.x. need to be censored!?
EDIT 2: Is there any chance you can put an experienced parent as the main driver and you as a named? Should save a bundle if possible.
