I agree. After age and weather oil leaks are going to happen. If you’re not making any payments on these cars that’s $$ in the bank every month. You’ve got two good makes, an Acura and a Toyota, and they are both built to last 250K at least.
The only time I have gotten rid of a car is when it needed catalytic converter and exhaust system repairs that could potentially cost more than what the car was worth. The last car I replaced needed catalytic converter repairs (the car had 3 - did it need just one or all 3? I didn’t even find out. I knew it needed one for sure and that would be at least $500.) Plus it had a bad, slippy steering rack ($800) and needed rear struts ($500). Plus it burned oil like mad. I had to add a quart every 10 days. And the transmission was starting to get slippy.
I would keep both those cars. If you maintain them, garage them if possible, and fix things when they break, you’ve got many more years of life in those cars.
