I did find the quote very reasonable, a few quid cheaper than I expected. This is using my full NCD from my current policy.
£70 in the old sky rocket is great the bad side squeaky is if you go back to having a car you can't take you NCD back with you.

(Apparently)
Not sure what you mean by 'mirror bonus' Marc. Can only use NCD on any one vehicle at a time may be wrong though.
