The thing is, the other owners' characteristic doesn't have to be Exactly as mine - enough to be similar.
You were willing to share and it helps me that way:
*you have similar characteristic to mine and a cicvic car OR a car in the same class as civic *and you paid 248UKP for your insurance last timeRight?
Great big thanks for sharing then! And even greater big thanks for sharing if you live in London (I don't know if other big cities in the UK have similar prices for insurances, might be taht they have) and have the same class car as civic.
