I guess you only had bad luck with that car. In 3 years and 30k miles (have 98k now) I changed the coolant tank, one cv boot and the intake sensor. The water pump, belts and the thermostat were my choice, preventive maintenance. The car had one window regulator changed by the previous owner and to my surprise I still run the Michelin tires that I got the car with. I was offered 7k in a trade for my 2001. If anything major breaks (engine failure or transmission) I'll just disassemble the car and sell it parts. I won't even bother to spend $4-6k for a car that is worth only a couple of thousands more. A car is ONLY a car. If it does the job then is OK. If not, I get rid of it and move to another one that fits my budget. In your shoes I'd get rid of it. I bet you cannot even enjoy driving it watching the cluster to see what's next.
