Buying a used Lexus LS600H: what to check
These checks follow the Lexus LS600H’s own MOT record: the areas it fails on most often, and how that changes as the car gets older. None of them replaces a mechanic’s inspection, but they tell you where to look first.
The biggest drop in pass rate for the Lexus LS600H comes between 6–10 years and 10–15 years old, from 100.0% to 93.3%. If you are looking at one in or just past that range, read its MOT history closely.
By mileage, the steepest fall is from 60,000–90,000 mi to 90,000–120,000 mi: 95.4% down to 88.7%. Mileage matters as well as age, so compare the car’s recorded mileages with its year.
1. Tyres
Recorded in 41.4% of failed Lexus LS600H MOTs. Rare on young cars, but 4.2% of tests at 10–15 years failed on tyres.
Check tread depth across the whole width of every tyre, including the inner edge. Uneven wear can point to alignment or suspension problems. Look for cuts and bulges in the sidewalls.
2. Suspension
Recorded in 30.3% of failed Lexus LS600H MOTs. Rare on young cars, but 3.8% of tests at 15+ years failed on suspension.
Listen for knocks over bumps and speed humps, and check the car sits level. Push down on each corner: it should settle rather than keep bouncing.
3. Brakes
Recorded in 30.3% of failed Lexus LS600H MOTs. Rare on young cars, but 4.1% of tests at 15+ years failed on brakes.
On the test drive, the car should stop straight without pulling or juddering, and the handbrake should hold it on a slope. Look through the wheels for scored or heavily lipped discs.
4. Lights and electrics
Recorded in 25.3% of failed Lexus LS600H MOTs. Rare on young cars, but 2.8% of tests at 15+ years failed on lights and electrics.
Walk round with the lights on: headlights (dipped and main), indicators, brake lights, fog light and number-plate lamp. Check the dashboard warning lights come on with the ignition, then go out once the engine starts.
5. Bodywork and corrosion
Recorded in 9.1% of failed Lexus LS600H MOTs. Rare on young cars, but 1.3% of tests at 15+ years failed on bodywork and corrosion.
Look underneath and along the sills for corrosion, especially near suspension and seat-belt mountings. Uneven panel gaps or mismatched paint can indicate accident repair.
Check the car’s own MOT history. Averages describe the model, not the car in front of you. Look up its registration for past failures, advisories that were never fixed, and gaps or dips in the recorded mileage.
Ask for the service history. Invoices show what was done and when; a stamp alone shows less. See how to check Lexus service history and what a service history check can tell you.
