Hi Dan,
Yeah pretty much like for like - only difference is that I was on a "limited mileage policy" with AF. All other details were the same.
Ended up going with Aviva, who were even cheaper (off the comparison site), they were £482, with another £60 cash back by quidco, so for all intents and purposes around £280 cheaper!
I'll DM you the reg number if you want to take a look, tbh I don't think the guy on the phone seemed all that interested in getting the price down so he just cancelled it.
