This is a very general question addressed to everyone in here that has done some mods to theirs C-max...
Have you declared any of the mods fitted?
I mean even the silliest , most minor ones like aftermarket carpets, pedals, gear knobs, handbrake covers etc etc?
You would be amazed how many people have been done for little meaningless things by their greedy, bloodsucking insurance companies
Try searching the internet and you will find that according to the 'rules' anything on the car that is non - standard is classified as mod
In theory it makes sense but where would you draw the line?
Could you also share how much premium did your declared mods attracted if any?
