If he still lives here in CA, he can easily get $1000 over blue book for a clean Toy, even if it is stock. '89 & '90 X-cabs sell for about $5k out here, some list for $7-8K. Last year I sold 2 "86's one a std. cab and one an SR5 4-Runner. I got $3500(asked $3800) for the truck and $4k(asked $4500) for the Runner plus an '85 2wd X-cab in trade. I cleaned up the X-cab and sold it for $2500. Both of the 4x's listed at or below $2800 in good condition for my area, both had a little more amenities than stock, bumpers, sliders/nerf bars, but not much more. Asking $1500 over KBB, will allow him to com down some and still make mnore than KBB, providing he isn't in a hurry.
