I have many of the same concerns as you. In my neck of the woods, parts and dealer support isn't so conveinant either . And with the closest dealer to me closing (1 hour away) , I don't expect things to get better.
I can say that this is the best bike I ever owned, it makes decisions a bit more complicated.
Since I already own one , there are a few options:
1. Try to sell it. The current market for MV in my area isn't so good. MV dealers around here aren't even interested in mine as a trade in, so what does that tell you? It's not like my bike needs to be reliable transportation for me. I also own it outright, so it's not like it costs me anything. I'm less inclined to sell..
2. Tool up and gather parts. This is what many seem to do, and immerse themselves in the hobby. Not really a bad way to go if you have some mechanical acumen . Parts will always be available. But best to stockpile the harder to get stuff and the basic tune up parts should be easy to get.
3. Sit back and wait for things to really get better for the company . Just be prepared for the the fact that things might not ever really improve.
I won't be in the market for a new MV until they appear to be more stable. Just my .02
