Cheaper to keep and maintain 2 very old cars (vs 1 newer one?)

I had 2 older cars, a 1995 and 1991 with theory nice to have a backup.
I decided it was better to keep the 1995 with 65,000 miles and do
meticulous maintenance to reduce chances of break downs. I am thinking
with proper maintenance I can at least 150,000 miles out of it. I
found with 2 cars I ended up driving the one most of the time and the
other one sitting idle for long periods of time, which is not good on
a car either.

I now do not have to license, insure and maintain 2 vehicles and think
it makes more sense financially.

I have the 1995 paid for but still make car payments to what I call a
car fund account. Hopefully by time my car dies, I will have a good
chuck of money to put down on new car.

My best advice is crack open the owners manual and follow maintenance
schedule and car should last. Although some cars are not all that
reliable and a transmission or major engine problems can throw the
budget out of whack. I am always envious of those people driving cars
with over 200K and still running fine. (Mostly Hondas, Toyotas,
Nissans)

Just my 02 cents
