Hi Cochyn,
As per my reply to your PM.
We are able to mirror NCB to a 2nd car providing it's a performance car (or modified car) with a limited mileage requirement.
Your best bet would to be to look at some mainstream providers (ie. Swiftcover or Esure) for covering the 1.2 Clio, run the quotes on the basis that you're going to be using the NCB with them and check the end result.
It would mean potentially changing your existing Insurance for the Focus Cosworth, but providing your driving history (accident/incident) record supports we would then be able to mirror your NCB to the Focus (being the cherished, performance/modified car).
This would work, but it will mean looking at both policies rather than just the Clio 1.2.
Again, as per my PM - if you drop me a PM with your contact details (or call 01277 376000 between 9am-6pm) we would welcome the chance to help.
Kind regards
Tony
