For things like that you need a specialist insurer that understands specific models. They normally ask for a written valuation from a specialist. I.e. k-tec.
High street insurers don't normally offer this, you would need to go through a broker.
Thanks. I'm interested but was hoping you would be a bit closer. I'm near Newcastle.
I'll struggle to view before 23rd so doubt it will still be available then. Looks a tidy example GLWTS.
