Crushers gets right to the point. He may come off as harsh , but he is really a nice guy (we met at River Shiver in 07). He knows his s*** and is dead right. Don't let the pretty outside fool you. There is something not right about this truck... or somethings.
I would not trust a dealer to know anything about a truck this old... especially at a Toyota dealership. He just wants to sell a car and make a commission.
Rusty frame, speedo cluster missing a screw, dash light wires hanging down, rust in the corners of the rear door jamb and rust showing along the inner wheel well under the right jump seat.
The great paint and dirty engine bay, dirty hubs and visible rusty frame screams nightmare. There a quite a few other FJ40's out there that are much better candidates for what you are looking for. A solid frame with clean, quite running gear are good candidates. Minor rust are easy fixes on a 40 since the panels are mostly flat (few complex bends) and are fairly thick (16 gauge to 76 or 78 and 18 gauge later). I personally think a late 78 and up are the best years for a 40, certainly engine and drivetrain wise.
