i have a 1992 3/4 ton extended cab with the diesel. i got lucky though, got mine for $1 from my father in law. mine is 2wd (well 1wd no limited slip) but i have been very impressed. my mileage is at 109000 right now which i'm sure others will chime in, is nothing for this engine. i was reading a thread somewhere yesterday where a guy claimed 1,250,000 and still trucking on a first gen dodge.
onto looks... i had to learn to love it... but now i can say through and through i love the look of the first gens. the picture posted is not my truck, i don't have a good shot of it, i will post one of mine tomrrow. as far as a price, i've seen people ask $9,999 for a 2wd with 220,000 and i saw one the other day for $2250. you didn't say if you are buying or selling. if you are buying, you might get a good deal since the truck doesn't appeal to most. if you are selling same situation applies only it's to your disadvantage.
ok i've rambled a bit... here are my final thought. if the truck is in decent shape $5,000-$6,000 for 2wd and maybe a little higher for a 4x4. as far as good or bad things to say.... i only have good things to say, if you like power, you've got a bunch stock but you options are practically limitless. longevity is amazing you can't go wrong with the CTD just keep the body together and the motor will last forever.
