Here are some factors that will skew all your calculations for cost of ownership… In 1985, my wife bought a new Toyota Corolla LE for $7,100. We kept that car for over 40-years and donated it to Eggleston Services (the Disability Employment Services Company).
Here is the posting for that donation…

Now, here is where this car, and our 2019 Toyota Corolla, and 2020 Honda Fit, skew your calculations…
We bought these cars from two dealerships that give Lifetime Oil Changes and Lifetime State Inspections (and other perks too…).
The '85 had over 50-oil changes over 230,000 miles, and 40-state inspections during our ownership. If you figure the oil changes 40-years ago cost about $30 and today’s oil changes cost about $80, then the average cost works out to about $50 each times the 50 (or so…) free oil changes that that saved us about $2,500.
The '85 had about 40-state inspections and back then they cost about $10 and they cost $20 today for an average price ot $15 times 40 free state inspections saved us an additional $600, for a grand total of $3,100 ( and that does not even count the all the Free Coffee and donuts, they often served…
If you glanced at the included link, you would have noticed that the car sold at auction for $4,500 and if it had been a private sale or at a Vintage Car Auction, it might have gotten $6,000 or more…
So, the moral is: Shop Smart, get lots of Free Perks from the dealer, and take care of the car.
Granted, the cost of gas, tires, insurance, etc… are not included in these calculations, but the final sale price, $4,500, and the Dealer’s Free Perks, $3,100, actually add up to more than what the car cost new…
PS: the wife named the car " Eleanor…"
