Hi as you have seen i have modded my car and just had a new quote of £531. I am 32 full no claims, do you think this is a good price or should i hunt around more? Thanks.

Have you tried Adrian Flux and Green light? So far they haven't been any good for me but plenty of people have had very good prices from them, drop a message in there section of the site and see what they come up with because £531 sounds expensive to me at 32 years of age and full NCB.

How much has your insurance gone up by since modifying your car, and what modifications have you undertaken ?

For your car, age and ncb it sounds expensive, however, most Manchester post codes are higher than average risk. 

I'd hunt around a bit more I'm with green light for about 400 and am 29 with a fair few mods.
