Importing insurance

[TVR_CS]

All being well I will be importing a 360 into the UK. The garage have offered me fully comp insurance with a 2K excess to drive it back but was wondering whether just to be safe, to get my own insurance so I am more in control if anything bad happens, with the bonus of dealing with a UK company.

Having never done this before, with VIN based insurance for importing, is this purely say, a 7 day policy or a 12 month policy that converts from VIN based to a standard UK policy having imported and done all the DVLA stuff?

Also any recommendations for insurance

Thanks
