why would it not be declared on your insurance.
its the same as any mod, if you don't decalre it your insurance is invalid simples
Imagine what the insurance comapany would say when you tell them 'I have a retracting number plate'. Most I think would say 'go and get your insurance elsewhere'. Great idea for shows and top marks for originality and design, but may be difficult to get your car insured with one of these. Just an observation.
doubt it buddy told my insurance and they said not a problem added it to my very long list of mods and at no more cost
Well, that's my observation out of the window then Some mods you would think insurers would frown upon end up with them not blinking an eye at.
