If you have common ICE car, it is very inexpensive to keep it running when you can wrench yourself. I spent less than $600 in 15 years and 160k miles for all parts to repair 2005 Malibu. I had to go to dealer once, because ABS control module is locked. You need dealer codes and 'programming'. $240 for 15 minutes work.

For 2005 Malibu:

Oxygen sensors: one is $19, still running on originals.

Catalytic Converters: one side Carb Compliant $319, still running on originals

Spark plugs: Iridium NGK 6*$5, took me 1 hour to replace

Thermostat: $4 + $3 shipping, 15 minutes to replace

Mass air flow sensor: still original $62
