Talking about electronics, I bought the PCM from totaled car and it works pretty fine. That car was in an acident. I payed just $50 +$15 shipping cost.
But I never gonna buy electronics from flooded car. Yes, you can dry it. But a water has a salt, dirt and who knows what else. After time small conductors on a plate will have corrosion. But the worst thing is that problems with electronics moduls really hard to find and diagnose. If the PCM will start mulfunction, believe me you'll change it last.
Other example about tires.
It happeneds I damaged a side of a tire while parking. It wasn't reparable. Other three tires weren't new but still can get another 20K. What the choice? To buy all four new tires? To buy just one new tire? I bought a tire exact like others, just may be a bit better on a junk yard for $40 with balancing and installing. Still have these tires.
