You're looking for a very specialized buyer with all the mods which means it will take longer to sell. I'd say [MENTION=121759]Davy180[/MENTION] is about right in the 10-12k range because 200k miles and 2004.
less than 10k since I don't know what/how/who/etc did the mods or where it was beat on.
take all that crap off and you can get more from a pristine OEM looking 4runner.
and that is how most will look at it, with maybe 1% of people interested in your mods. and of those that off road, they will be suspect since they didn't do the offroading or mods themselves.
Sadly I have to agree with the above and I am speaking from experience.
The first thing you have to realize about selling a modified vehicle is that your "pool" of buyers is a fraction of the size of the pool of buyers for a non modified vehicle. That drops a lot of value right there because there simply won't be as many people competing to buy it.
If you want to get any value out of your mods your smartest bet is to take them off and sell them separately and return the vehicle to as close to stock as possible.
I seriously doubt anyone's going to pay $10k for a vehicle with 200 grand on it no matter what modifications it has.
Just as a point of reference I tried to sell my 4runner before I left for my next camping trip. Mine is 3 years newer (2007) and has 60k fewer miles.
The highest offer I got was $10k and that buyer ended up backing out. My truck is not beaten up, although neither is it in perfect, flawless condition (and I'm betting yours isn't either, not with 10+ years and 200 grand on it.)
Also yours is a 2004 which means it has the 4 speed auto vs. 5 speed.
The only way to really know is to put it up for sale. Clean it up, take some nice pictures and list it. But don't be surprised if you get people emailing you or texting you and asking if you'll take $6k for it.
I understand you may have an idea in your head of what YOU think it's worth (because I did, too.) But reality has a way of slapping you in the face.
Around here you can get a fairly clean later 4th gen (2006+ facelift) for about $12k with ~ 130,000 - 150,000 miles on it. I've even seen V8's in this price range.
