Yes, been placed on hold several times for the sales guy to check and double check on this, I've been advised about the following extras:
1. In case of claim, fault or non-fault, the insurance will cover: current market price of the car + current value of the mods
2. non-fault claim: courtesy car provided
3. comprehensive cover in Europe for up to 60 days
4. fault claim: excess fee will be deducted, but separate claim for the excess fee and I should have it all returned. allowed only once per year
