Id put the $ into maintaining this car. Hypothetically 3-5k and you will get 2 more years..youd spend FAR more on 2 years of car payments.

Turbo likely fine, look for air leaks...might be repalted to EGR and pressure sensor codes 9did someone actually diagnose these or just guesses based on codes?)

Control arm is probably just a $60 bushing, whole arm can be replaced the next time.
