Just out of interest and if any dealers read this they might be able to answer my question,Landrover would have had my car for 3 weeks at the end of this week how long would you say is fair to find a problem with my car before I start asking some serous questions as I go away this week with the family for 10 days and would have liked to have gone in my own car instead of the courtesy car...problem with vehicle is vibration through the gear box...manual gear box...

Sorry misread that! But get asking!

If courtesy car is not equivalent to your FL2 and they can't give you an FL2 phone customer services and they can authorise a hire car.
If your vehicle is under 1 year old write to the "Dealer Principal" and state that you wish to reject vehicle under sale of goods act. All FL2's (3) Gone
