IMO your best bet to find a deal is to line up a skillset(buddy who will work for beer and pizza), such as electrical, and look for one with defects in that area(electrical seems to scare many away, but they really have a pretty straightforward electrical system)... Everyone bids on the ones that have a clean report so they go for a premium. The partial basket cases get less attention and go for much less.
Mine had a bunch of electrical issues and a decent drivetrain, needs some door work and parts. Only two of us bid on it and I had the electrical issues resolved and or identified in the first week playing with it. Only needs a turn signal flasher now... in the end it will still have far less into it than my 2000 tacoma...
The fact is, you are going to pay eventually unless you build your own knowledge base to fix it yourself. The person who fixes them always learns the most about them so buy a cheap one and dive in... If you dont want to learn, or dont enjoy fixing things, better have deep pockets...
good luck if you should choose to accept this mission
