I've notice a huge price hike on insurance as well for my IS200. Last year i paid around the £400 mark, then i got the renewal for £800 !!! Shopped around and the cheapest i got was for around 550. I struggled to find anyone that wanted to touch it, both got clean licenses and we don't live in a "bad area". It's only myself and my dad that use it, ok so its got coilovers on it but the £400 rise was crazy. It's either the insurance companies trying to recoup the payouts from the floods and snow or they are just taking the ****.
