how much is my fj40 worth

might help if ya gave some pictures and info

Did you try www.kbb.com ?

kbb only tells u the value of vehicles up to 20 years old

All depends on the Cruiser (shape, rust, mods) as well as where you're located. A couple other places to check would be tlca.com (Toyota Land Cruiser Association), ccot.com (Cool Cruiser of Texas), or ih8mud.com.
