Buying a used Chrysler-Jeep 300: what to check
These checks follow the Chrysler-Jeep 300’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.
By mileage, the steepest fall is from 30,000–60,000 mi to 60,000–90,000 mi: 81.5% down to 71.2%. Mileage matters as well as age, so compare the car’s recorded mileages with its year.
1. Brakes
Recorded in 87.9% of failed Chrysler-Jeep 300 MOTs.
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.
2. Suspension
Recorded in 55.4% of failed Chrysler-Jeep 300 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.
3. Lights and electrics
Recorded in 44.4% of failed Chrysler-Jeep 300 MOTs.
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.
4. Steering
Recorded in 20.8% of failed Chrysler-Jeep 300 MOTs.
The steering should feel precise, without knocks or play, and the car should run straight. Turn to full lock both ways and listen for clunks.
5. Tyres
Recorded in 12.6% of failed Chrysler-Jeep 300 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.
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 Chrysler-Jeep service history and what a service history check can tell you.
