Age 47, QP 4.7, 8000 miles, sdp&commute plus business, me and mrs, garaged, 10yrs protected, Aviva plus cover, £404 total for monthly payments.I think it all depends on a variety of factors e.g. postcode, mileage etc.
I’m the same age as you OP, albeit with 13 years no claims, and a 4.2 (or 4.7!) is going to cost me around £600/annum.
