I've got a 1999 Corolla with just a hair under 200,000 miles on it. I bought it in 2004, and hadn't put any money into it at all (other than oil changes, head lamps, tires, a battery, and one set of brake pads) until about a year and a half ago, when I got the serpentine belt replaced. Since then I've also had to get both front calipers replaced, a new set of front brake pads, the wiring into the door repaired (for the windows and electric locks), and have a few other things that are non-mission-critical, so I've been not doing just to save the money.
The car starts and goes reliably, the undercarriage is rust-free, and I don't mind driving an old car. The clutch is probably going to be the first big-ticket item that goes on it, as it's gotten quite soft.
Anyway, while it's kind of a hit to have all these repairs in the last year (as well as having to get two new sets of tires), I'm still spending less than $100 a month on maintenance, which is definitely cheaper than a car loan. For a while I was ready to sell it and get something new(er), but I figure it just doesn't make sense money-wise. And, I drive a lot, so miles add up quick. Every year I keep this car is 18-20k miles I don't put on another car.
It looks like you have already spent much amount on your car repair and it still need repairing from time to time.
Therefore, it is a better option to replace your car engine with a new or used car engine that give you better output performance and long drive support too. Used are preferred more because they are inexpensive and renders similar performance like the new one.
