Hi,
Gap insurance can be good value when you consider what you pay annually for your car insurance and what it could potentially be worth when you need it most (write-off).
As for whether you should take the garage's policy or not, you should shop around as this is available elsewhere. Compare the price but equally, if not more importantly, compare the level of cover and any exclusions or terms of a claim.
Also, ensure you get the correct type of policy, depending on whether you pay cash or finance the vehicle...
Keep us informed of your findings...

You gotta tie yourself to the mast my friend, and the storm will end.
