Seriously considering buying an H1, but I have a few questions
 

My biggest fear is that something will damage my H1, has anyone had any problems finding parts for their hummer? Are there manufacturers who still make parts for them, or are you just SOL if you need exterior parts?

Is an insurance company very likely to total out an H1 for that reason? I don't want to sink $50,000 in a vehicle if it might get totalled for that reason.

Any general advice is also very welcome.
