Oooh - expensive. Have you tried moneysupermarket - saved £165 using them compared to Confused.com and Gocompare on Volvo 2.5 ltre who all wanted £500+
I've had a quote for our 1999 P38 2.5 today with Kwik-Fit , £281 for business use (building contractor) with my wife as named driver. One thing that may help is I only work locally so mileage is under 5000 per year.
