Watch your insurance
A top insurer has warned readers that some common modifications often applied to classics can add costs to your policy. A respray is one of the few aesthetic modifications that does affect your insurance costs according to Heritage Classic Car Insurance. Remapping or an ECU upgrade could also increase a policy – as could a change of engine. An engine replacement will have more of an effect on your insurance than remapping or respraying according to Heritage, but again, it depends upon insurance companies.
