Does anyone know what steel the affected main chassis tubes are made from? My suspicion is that they will be a mild low carbon steel tube or something equally cheap. It might have been better if they had used something like Reynolds 853, which is known for its high fatigue resistance. Cheaper in the long run for Morgan to have used the correct materials. I know of one M3W in Toulon, which went back to Malvern recently for the chassis to be repaired and was diagnosed as requiring a new chassis. Not a cheap warranty job, albeit that Morgan is saying they will not pay for the transport.
