yeah my advise would be aviva/RAC day insure doesnt matter which one both nearly identical and the two companys ever share an office together

there are other ways as if i remember if you buy the car from ebay and pay there rates you get 7 days free insurance

and i dont know if its still going but at aviva/RAC were offering 7 days free insurance if you take out a quote with them so worth a call to see if they still do that
