Hello all, nice forum which has been very informative prior to me looking for a Copen 600cc. Found one this week but after checking it over, speaking to the owner and checking previous MOT data it seems to have had a major issue with rust and corrosion all under the chassis and in the boot failed several MOT's over the years but corrected and passed subsequently including the current one which has now passed after rectifying the advisories on corrosion. I know they are prone to corrosion due to UK road salt/weather etc but is this a normal amount each year for the last 5 MOT's? as it has never been under sealed. Only has two owners from new and a 55 plate a bit tatty inside but reflected in the price and I'm looking for a project and this seems to be it just need to know if this amount of corrosion repair is a no no! Any advice welcome on your experience with the rust and costs approximately for chassis welding and under seal? Much appreciated!
