As some of you know I've recently added new bumpers, sills, quad exhaust and alloys. I was with Privilege Insurance and my renewal was a reasonable £540 until I told them of these additions.
Basically they were happy with everything except the alloys and wanted to charge me an additional £189 per year. That's 35% extra for a set of wheels. I've switched today to Norwich Union for £511 per year including all the modifications. Luckily I was in the honeymoon period of 14 days to renew with Privilege, so managed to cancel with them at no charge.
So, don't use Privilege if you car is modified or intend to modify it.....
