Well this forum is full of helpful folks and full of great information.
However, you Mr Mason with your whopping less than 20 posts told one of our biggest contributors to GTFO your post?! How dare you. Maybe you should read up on forum etiquette.
JD has done way more stuff to his explorer and ranger than you could ever dream, his totals equal well more than 20 grand in mods. He has bought and sold more stuff than you could ever dream of, has helped countless folks on here. I will stick my neck out and say HE KNOWS WTH HE IS TALKING ABOUT.
Back to your lifted explorer with a bad engine, stock crappy automatic, lift and new tires. To me it is worth ummm a grand because it need 7-800 in engine work, not counting axle re-gearing, and ditching the auto for something better.
How do I know it needs 7-800 in engine work? That's because I just did it to mine 6 months ago. That doesn't count a radiator, and a water pump. (I address the entire cooling system at once.)
So to get the most for your money, part it out, and then drag the explorer across the scales and crush it. Or accept the offer already presented to you.
You do realize you asked all of our opinions on what it was worth, and you wont always agree with our answers. You should respect folks that have more knowledge than you. JD's almost 8k posts aren't just fluff, it is real facts. If anyone has more knowledge with a modified 91-94 explorer/ ranger it is him.
