HIC always sorted me out. Try and get it on classic insurance as that will be cheaper and limit your mileage.

I bought mine when I was 26 and paid adrian flux £210 0 for a fully comp policy (not classic). Then the following year went to HIC and it was £1500 and year after that 1000, then 850 and finally waqs quoted 650 this year.

All mods delcared to 400bhp too.
