Strange, my dealer have said that they can do this and I'm pretty sure they won't be the UK specialist. From reading the article it doesn't sound difficult?BMW stated to me when I visited them in London that all carbon repairs, so that is repairs to the Life Module, must be done at their specialist repair centre. There is only one of these in the UK at the moment... don't know where it is though.
With the MINI it was more complex than that, and I imagine it could be for the i3 too, hopefully not though. The insurance cost to the owner didn't go up, but apparently due to large, unbroken body panels on the first generation car, costs to repair (usually replace) where much higher for small incidents than insurers had expected or prepared for, not considering the individual nature of the car. This (from what I was told) lead to pressure to change the pressings and construction to more modular, smaller parts to reduce insurance repair costs. The consequence of BMW not doing this could have been higher insurance costs/ratings.As for insurance, they've always said 'comparable to a 1 series' and the quotes I got started at just over £300.
