The mods put on about £60 to the premium Jeremy...which isn't bad really. Some insurers though react rather badly to the very hint of modifications...as though you are a boy racer! I've been quite impressed with Morgan Insurance (Headley) over the past couple of years. Gott & Wynn gave me a slightly lower quote but would charge me an additional premium for trips up Shelsley Walsh and Prescott etc whilst Headley cover me without charge.
I'll be there Saturday!
