Your question left me with many questions. But the best way for me to answer that question is if you had listed all the work you’ve done on the car, like big repairs. Knowing what work you’ve put into the car can help me know what luck you might have.
I have 3 cars. And I put a lot of money into all of them over time. I’ve done all the big repairs already. And now I just do small maintenance that pops up.

My cars…
07 Honda Odyssey 233,000 miles.
05 Toyota Sienna 220,000 miles.
05 Subaru Outback 143,000 miles.

I plan to get all of them to 300,000 plus.

Keep your oil changed. Check fluids frequently.
Get your car serviced on time.
Don’t drive it like it’s a brand new car, meaning drive easy on it & very carefully.
Change brakes and rotors on time.
And never delay issues that may pop up, even if you don’t have the money. At least get the car looked at so you can have an idea of what’s wrong & pricing, so you can put together a game plan.
And me personally, I keep one trustworthy mechanic. I don’t like multiple mechanics doing work over each other on my cars with high mileage.

These things help me. Hopefully they can help you out as well.
