Buying a used Mclaren 600lt: what to check
These checks follow the Mclaren 600lt’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.
1. Number plates and VIN
Recorded in 24.1% of failed Mclaren 600lt MOTs. Rare on young cars, but 1.1% of tests at 3–6 years failed on number plates and vin.
Match the registration plates and the VIN (usually at the base of the windscreen and on a door pillar) to the V5C.
2. Lights and electrics
Recorded in 24.1% of failed Mclaren 600lt MOTs. Rare on young cars, but 1.1% of tests at 3–6 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.
3. Exhaust, emissions and leaks
Recorded in 14.5% of failed Mclaren 600lt MOTs.
Look under the car for fresh oil or coolant, and listen for blows or rattles from the exhaust. Watch for smoke from the tailpipe when the engine starts and when you accelerate.
4. Tyres
Recorded in 14.5% of failed Mclaren 600lt MOTs.
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.
5. Suspension
Recorded in 7.2% of failed Mclaren 600lt MOTs.
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.
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 Mclaren service history and what a service history check can tell you.
