Worth seeing, inspect hard
At 155,000 miles and $24,500, this GX 460 Premium is priced above where high-mileage examples should land — the 1UR-FE engine's timing chain cover oil leak and valley plate coolant leak are both well past their typical onset mileage. If the seller has receipts for either repair, the asking number is reasonable. If not, $20,825 is your opening offer and $20,300 is your walk-floor.

No engine bay or under-vehicle photos in the listing — for a high-mileage 1UR-FE, the oil seepage pattern is what you need to see.
Seller says "well maintained" but doesn't name service intervals or attach receipts.
Mileage is rounded ("155k") not exact — typical of a private seller who hasn't looked at the odometer recently. Confirm at the meet.
No mention of timing chain cover or valley plate work — at 155k these are both due or already failed.

Timing chain cover oil leak
Past 120k · likely already due
$1.8k–$2.8k
The 1UR-FE 4.6L V8 develops a slow oil seep at the front timing cover gasket. Typical onset 120k–160k miles. Not catastrophic but visible from underneath and worsens with heat cycles. Fix is engine-out labor — most of the cost is hours, not parts.
The 1UR-FE's valley plate (under the intake) develops a hairline crack at the rear coolant passage. Symptom: low coolant level with no visible external leak; sometimes a faint sweet smell on hot shutdown. Onset typically 130k–180k. Catch it before it dumps coolant into the V of the engine.
The Kinetic Dynamic Suspension System (KDSS) sway-bar disconnects rely on a sealed hydraulic accumulator. By 150k it commonly loses pre-charge — the truck still drives but body roll increases off-road. Recharge service (no parts swap) runs $300–$600 at a specialist.
Shared with the 4Runner and FJ Cruiser, the front lower ball joints wear out around 120k–180k. Symptom: a faint clunk over speed bumps, sometimes uneven inner-edge tire wear. Catastrophic failure has been reported on neglected examples — replace both sides together, then get an alignment.
A first message, a negotiation script anchored to the math, and the open questions to clear before you drive out.

SEND-FIRST MESSAGE
Hi — interested in the GX 460. A few questions before I drive over: 1) Have you had any work done on the timing chain cover or valley plate? Both are due-or-done on a 1UR-FE at this mileage. 2) Any KDSS service history? 3) Have the front lower ball joints been replaced? They tend to wear past 120k. If everything checks out I can come this weekend with cash. Thanks.

NEGOTIATION SCRIPT
I'd like to offer $20,825 today. Comps for clean-title 2017 GX 460 Premium with 150k+ miles in Southern California sit at $19,500–$22,000. That number assumes the timing cover and valley plate are original (which the absence of receipts suggests). If you can show me either repair was done, $22,000 is fair — I'd want to see the work order. If we can't get to that range I understand, but $20,825 is my real number.
— anchored to walk-floor $20,300
