While not a 4X4, I picked up my '93 Dakota last year. It currently has 166K on it. It has the V6 and auto.

I don't think it spent its entire life used and abused, but, I know the last owner wasn't too 'kind' to it.

I did the usual maintenance to it when I got it, updated the plenum gasket, and repaired a few things outside 'normal' wear.

It still has a couple of quirks that I haven't been able to figure out if they are electrical or fuel related, but, it has never left me stranded.

Biggest issue until recently was the AC not working. Now I may have to redo the intake gasket

BUT, despite its quirks, and its scars, I love this thing. It rides decent, its comfortable (to me anyway) and its not 'stupid big' like anything new.

The V6 is no powerhouse for sure, but has no issues keeping up with or passing traffic. I admittedly drive with a heavy foot and it gives me consistent 14MPG in almost 100% in town driving.
