That's exactly what they counted on.
Incidentally, the dealer miraculously found the time to get back to me after I raised the issue with the factory. They claim they never received the September 3rd email due to a server issue, and hadn't replied meaningfully to the one dated August 15h due to a family emergency. Make of that what you will.
What followed was a bunch of lies and comical cya obviously meant for the factory. They called it "defending our dealership from your public compliant." Nice try, but I have everything well-documented and in writing, so there will be no false narratives about either the purchase or the car they finally delivered seven months late.
Bottom line is I've been "invited" to work with them "to increase my satisfaction," but "any defects or problems will be addressed with the factory. They may be covered under warranty, but the factory will make that determination." In fact a classic Morgan "they all do that, sir" was tossed in for good measure: "You are calling factory assembly techniques and common characteristics of the 3-Wheeler 'defects.' These are not defects." . I offered to relate which of the remaining defects they considered characteristic of fine Morgan craftsmanship on the storied 3-Wheeler; but I guess cracks, lights falling off, torn boots, and visibly damaged parts on a new car would be a pretty tough sell, even for Morgan. So much for "we're not like that."
I'm going to give them a fair opportunity to rectify all the problems that remain in the sincere hope of getting past this in a friendly way and maintaining some kind of relationship with the Morgan factory. We'll see what happens.
