People throwing money at cars to try to fix issues without actually using any diagnostics or common sense... or just doing that then selling a car cause of small issues they can't figure out and won't listen or ask for advice on.
Its a thing. Very common. I bought an 86 lebaron GTS for cheap because it had no heat. Two hours after i bought it you could cook a chicken in that car. Plugged heater core.
They did stat and water pump and didnt want to put any more money into it thinking it was a bad head gasket.
My buddy bought wheel bearings because one tire was wearing different than the other.
Winter tires, drove across the country and never rotated them since new.
