Mohammed,
First of all, fancyacar.co.uk does not sell car insurance. For you to get
car insurance for only a couple of days, you will need to be at least 21 of age and since you're only 18 at the moment, no insurer will be willing to take you on.
For your age, the minimum insurance cover you can get is one month. If you would like to know which company will insure you for that period, then let me know.
