A 2020 Toyota Land Cruiser is now 6 years old, so an average example has covered around 81,000 miles. A late-run car · the most reliable part of the generation, but higher-mileage wear items are usually the deciding factor. Check the state safety inspection and service history alongside the documented faults below, which are sorted by whether a 2020 car has usually reached the mileage where they appear.

The 2020 Toyota Land Cruiser is 6 years old, so an average example has covered roughly 81,000 miles. At that mileage most documented faults are still ahead of it, so servicing evidence matters more than wear. A further 3 typically appear later in the car's life.
Age, electronics and build-related issues that are not mileage-driven.
Underbody and chassis corrosion on older cars
Typically appear later than this year's average mileage · worth budgeting for rather than inspecting.

Chassis rot. Walk away rather than negotiate.
Strongly, which makes condition buying worth it.
