Here’s some advice that may or may not help
Whatever car you do buy, treat it as if NO scheduled maintenance has ever been performed.
That means it’s probably due for a timing belt, valve adjustment (EVEN IF THEY’RE NOISEY), spark plugs, air filter, coolant service, brake fluid flush, fuel filter and a transmission fluid and filter service (NOT A FLUSH)
I’m sure I probably left something out, but you get the point, I hope.
Another important to remember.
If the maintenance manual says to replace the timing belt at 60,000 miles OR 8 years . . . that means that every 8 years it’s due for replacement, regardless of if you’ve driven 60,000 miles.
Yet another point to remember.
Valve adjustments are critical. Noisey valves obviously need to be adjusted. However, valves that are not noisey are not necessarily fine. Valves that are too tight will make NO noise, and they will eventually burn up. At that point, the cylinder head needs to be sent out to a machine shop.
Don’t let a shop talk you into a transmission fluid flush. Drain and refill is the best way to go. Of course, you should also remove the pan and replace the filter. Flushes are easier and more profitable for the shop.
Use only the correct transmission fluid for your specific car. NOT a generic multipurpose fluid.
Have the maintenance performed when it’s due. Don’t delay. That way, you’ll hopefully always have a fine running automobile.
It’s best to keep up with repairs, rather than to let them pile up. After all, who wants to drive a car with non-functioning AC, a bad battery, 4 failed window regulators and a rusted out muffler? These things obviously didn’t all happen at once.
I agree with @twotone about setting aside money each year for maintenance and repairs. However, if you don’t spend all $1000 this year, don’t spend the remainder on other things. Let it accumulate. That way, if you need a transmission rebuild in 3 years time, you might already have enough money set aside.
