Mike the centa compensator parts are £834. Early chassis should have had a bolt in brace behind the engine but this may not stop the fractures as my 2013 still broke & has just had a new chassis which Morgan paid for. Early cars also needed a so called steering comfort kit but most have had it done, around £175 I think. The rectifier is a weak point but a Harley D part is about £80 rather than £250 from Morgan.
You say you do not want to tinker but its not a Toyota & will need frequent checks on oil & strange noises etc. There are many things you can do to make it more comfortable like raising front of drivers seat with a batten & sealing gaps behind seats to keep dust out & sound proof there. A full width screen from Fairbourn Carriages should be considered. All these are DIY or you can pay someone.
