I have been taking care of machinery since I was eleven years old. Most of that time was for money. As a ship's engineer one gets to see the price of poor maintenance very first hand.
So, I still tend to over maintain things. Our current cars have 188 and over 200K on them (I am unsure of the later because the odometer broke and I had to track mileage with a GPS that failed at something over 200 - then I found a good speedo in a wreck).
I have two different garden tractors by the same manufacturer and one is 58 and the other is only 50 years old. (Hours on each? I have no clue.)
Our coach is a 73 with over 150K on it and we will soon be departing on a 3K miles excursion. I try very hard to over grease the suspension as even the 9$ a tube grease is cheaper than any parts.
Just try to balance the cost of maintenance with the cost of any repair. Even if you will do the work, it is still a sucker bet.
