It's frustrating for me when we see a Mahindra problem that is a couple thousand miles away and out of our reach. Pretty much all tractor problems are solvable, but if things linger too long, disappointments mount and it gets to the point that there is no fixing the relationship, even if the tractor is repaired.
The dealer profited on the initial sale, he needs to hang in there to resolve the issues. Now I do not know if there is "another side of the story", there often is, but even so - if a rep or a dealer says he will call or come pick up the tractor, and then doesn't do so, that can't be good for customer satisfaction.
Steve, sorry you are having such poor results.
