The Boxster insurance was up for renewal last week. Tesco quote came in at £363.00 , £40 up on last year ( 3000 miles a year policy). Checked on Compare the market , Performance Direct £161.00 . No apparent differences in cover . Cancelled my automatic renewal with Tesco and received a phone call from them asking why I was not renewing . "£200 difference and when the BMW ( apologies for swearing) comes up for renewal I will be looking elsewhere". Obviously no point in even asking them to price match such a huge difference.
