The renewal price for my 4/4 with RH this year is £496. It seemed a lot, so I gave Peter James a call and they have quoted me £357 - £139 cheaper. I'll try Gott & Wynne later today.
My tintop (Mazda 3) is also up for renewal. The Meerkats quoted me £297 against the renewal with the AA of £536, saving £239.
So I'm £380 better off already ... potentially more if G&W are cheaper. I was slightly surprised that the Mazda quote was with Direct Line; apparently, they have been on comparison sites since last year.
