Think you've just described exactly what a Morgan requires and it's not just slapping mod's on to the car in the hope that it will improve it or resolve a problem, that's asking for trouble! Rather, you have to look at the whole car and diagnose what is making it behave so badly and rarely is it one single thing!
New Elm's have a huge knowledge of Morgan cars, probably one of the most knowledgeable and skilled dealers there is and lets not forget true innovators as well! Tim is selling up as we speak and I do hope that a continuum of the business will go forward into the future and retain that skill and care.
I think the solution suggested to you, no, rather almost forced on you as a normal fix solution to the rear springs contacting the body work when clearly the problem lay with the crap springs bought in by Morgan from china, was in fact criminal. A little like loosing a wing tip on an aircraft and shortening the other side to match! It is a known fact that these springs were sub standard and IMHO Morgan should have had the decency to factory recall those cars for rectification. Your car of which is smack in the middle of that problem time.
It's reported that cars having had the springs changed almost on collection from new had been found to have sagged by the time the owner collected it with new same rubbish replacements. You did exactly the right thing in walking away from that dealer who suggested his fix. This is not banger racing and someone who buys and owns a Morgan is spending a lot of money regardless of what their entry level is. It seems the new CEO of MMC has finally started to get a grip on providing a new standard and corporate image at Morgan, yes, the new CX cars are out of a lot of current classic owners budgets, me included! and they have a much more modern feel about them but time cannot stand still.
Us clasic owners can only hope we get included in the changes in a good way and don't get our wallets felt in an unrealistic fashion!!
i truly believe, that those amongst us who have dreamed of owning a Morgan,, often for a huge chunk of their lives are so let down by poor service when finally they get that chance that they soon sell the car because it's not the ownership experience they had hoped for, in that it drives terribly, no one can resolve the problems for them quickly, easily or effectively and so a life long dream is destroyed. If you don't believe me then answer this: Why do so many dream Morgan cars have so many owners? It's not uncommon for these cars to regularly change hands between 1 and 2 years Now that's what I call a dream car!
