Im going to insure my RS cosworth, I want it for weekend and occasional use in the week to and from work so a few thousand miles as its going abroad too at some point, I want to drive it to and from car shows also.

Basically a stg 3 300bhp sapphire in a roll caged shell, no interior really, alloys and shiny bits and bobs and big brakes. I want it fully covered, who do I contact for best price.
Is it best on a 2x car policy or?? I dont know. I can email full spec to the company if required for a valuation thanks
