I've had my M710 for about 7 years now. A 73 so it's 40 years old. Yes it's a bit noisy, thirsty, (just rebuilt the carbs, there are 2) Non-stocks seats from a 93 Honda (very comfortable) installed a winch and bumper from EI (Expedition Imports out of Napa, CA) Some parts are expensive, but not as much as the newer vehicles on the road. I have driven it on some round trips as much as 3500 mi. Have to use GPS as the speedo died some time ago. Great to camp in and although a bit slow (55mph is my top on the flats) it gets me there and back. Since it is a slower vehicle I can use Re-treds from Treadwright at about $120 each they sure beat out fancy off-road tires. I understand there are some that complain that the vehicle is difficult to maintain, perhaps, but it is 40 years old and I do expect some items to eventually live out their lives. Keep the fluids up and do regular maintenance and it will be a great vehicle. Pinzgauers do not have the history of some of the US old iron but, they are used in a variety of conflicts throughout the world. The newer ones are diesel. Difficult to armor as it is a forward control vehicle and one is sitting over the tires. I keep it the original OD as it feels better to me and it does get lots of looks where ever I go. Happy trails.
