I think it might be worth taking a policy out.
I have bought mine back in beginning of the year, the car has found a coolant leak with warning on idrive, taken it into local dealership, found the water pump was faulty, replaced it under the insurance warranty.
Also, I have recently asked them via email, they seems to allow taking the car to service at any VAT register garage with genuine parts used (I might be wrong on this, and I would only believe until they send me a new policy booklet with updated wording, they said should be ready to be sent in couple of weeks)
Congrats on the move! saw your signature with a 135, the stopping power should be better with the 6 pots ?
