That's some crazy money going out. I still have a 2005 truck and a 2015 car I bought both new and paid off long ago - both low miles and well self maintained, so tons of life remains. Probably keep them at least 10 or more years ... have zero desire to buy something new or different. By not trading in and buying new vehicles every 2-3 years, I've probably saved a ton of money which I've invested and used for other necessary things. My neighbor never buys and does a lease that's not cheap ... always want's a new car, so he's just flushing money because he can't even get anything back if traded in or sold.
Nice strategy. My strategy is very similar.
I just bought a 2008 Toyota Corolla CE a few months ago from original owners (an elderly couple that are getting too old to drive) for $4,000. It only had 60k miles on it, and it had oil changes every 3k miles.
I'm currently using it as a commuter car, and plan to put 20k+ miles a year on it.
Some original owners of this generation Toyota Corolla (years: 2003 to 2008), have said on Reddit that they ran into the dredded 299,999 mile odometer stuck issue. But they also mentioned that in 300,000 miles, their car has only needed basic maintenance and a few repairs like starter, alternator (for example). Those owners also commented at how reliable their Toyota was from 200k to 300k miles. They never hesitate to take it on long trips. I think most other car companies cars would need a lot of expensive repairs from 200k to 300k miles, but not Toyotas.
Some other pluses about the car:
The engine has a timing chain.
Toyota timing chains never have to be replaced (so no timing belt or chain replacements to ever worry about).
Also, vehicle gets 40 MPG on the highway if driven with a light foot at the speed limit in warm weather.
Also, 2008 was the last year for the Toyota Corolla where Toyota specs 5W-30 in the owners manual.
So I can use 5W-30 and be following the owner's manual recommendation.
So with this $4,000 purchase I plan to drive the car from the 60k miles it had when I bought it used for another 240,000 miles until it reaches 300k miles.
I don't see any advantage to buying a new vehicle for $35,000 and driving it for 240,000 miles when you can buy a used vehicle for $4,000 and drive it an additional 240,000 miles. Also so many newer vehicles with the low tension piston rings burn a quart of oil every 1,000 miles. I didn't want to have to deal with that. All the vehicles I own have the normal tension piston rings and don't use burn or leak any oil.
