ABS actuator Repair worth it?

Let’s do some math. Your 180k salvage/branded title car in working conditions is about $2,800. (With a clean title $3,800 for a similar car but not yours). So spending $2,700 repair for a $2800 car is definitely not a good financial decision.

Actually, If you sell immediately the OEM catalytic converter in CA for $1000 and the 2019 OEM battery for a $1000 you can donate the rest of the car and along with your $2700 that you would spend on the repair you now have $4,700 for a similar Prius or Corolla, or whatever reliable economical car you like.
