2009 Chrysler-Jeep 300 3.0L Diesel · TS03 AMS

A consistent run of eight consecutive MOT passes with no recorded defects or advisories between September 2018 and November 2025 defines the roadworthiness profile of this 2009 Chrysler-Jeep 300. Across every annual examination from 2018 through to the most recent test on 1 November 2025, the vehicle has cleared DVSA inspection criteria without any component being flagged for monitoring or rejection, which is an unusually tidy administrative record for a car now in its seventeenth year. That said, a clean MOT history only confirms that the vehicle has not been refused a test certificate during the recorded period; it does not constitute a verified record of mechanical condition, internal service intervals, or non-tested components such as clutch operation, gearbox internals, engine compression, or timing chain stretch. The absence of any advisory notes over eight consecutive tests should therefore be treated as administrative cleanliness rather than as independent confirmation of mechanical integrity. Recorded mileage of 171,974 miles against a 2009 manufacture date equates to an annual accumulation of roughly 10,100 miles per year, which is broadly consistent with average annual driving for a car of this age. The MOT record shows uninterrupted annual testing from 2018 onwards, with no multi-year gaps that would suggest prolonged off-road storage, and no anomalous jumps in odometer readings between consecutive tests, supporting a continuous pattern of regular use. For a 3.0-litre V6 diesel or petrol drivetrain depending on the variant fitted, sustained annual mileage at this level implies meaningful cumulative wear on engine and transmission mountings, turbocharger and injector components on diesel derivatives, suspension bushes and dampers, dual-mass flywheel or torque converter operation, and exhaust mounting points. The lack of any advisories on these systems is worth noting, but a vehicle travelling consistently will accumulate wear that simply does not register as an MOT failure point until component thresholds are crossed. Given the absence of any historical advisories, the inspection focus for a prospective buyer should fall on the areas most likely to have aged out of tolerance on a high-mileage seventeen-year-old car but which would not yet necessarily have triggered an MOT defect. Particular attention should be paid to the front suspension, with a physical check of the upper and lower control arm bushes, anti-roll bar drop links, and front coil springs for cracking or sagging, listening for clonks over uneven surfaces and feeling for imprecise directional changes through the steering. Brake pedal feel should be assessed for excessive travel or sponginess, and the wheels examined for evidence of binding calipers such as uneven pad wear or heat-discoloured discs. On a test drive, listen for any diesel-specific clatter or timing chain rattle on cold start if the vehicle is the common 3.0 CRD variant, monitor for smoke from the exhaust under load, and check the automatic gearbox for delayed engagement, flare between ratios, or harsh downshifts. Underbody and structural integrity checks are especially relevant for a Chrysler 300 of this vintage and mileage, even though no corrosion has been flagged on the MOT record. A physical inspection on a ramp is strongly recommended to examine the front subframe, rear trailing arm mounting points, brake pipes along their full length, fuel lines, and exhaust system for any surface corrosion or weeping joints that would be hidden during a standard MOT visual examination. The rear brake drums or discs and the parking brake mechanism should be confirmed to hold the vehicle on an incline, as parking brake performance is a common wear point on cars that have covered substantial mileage. Finally, all fluid levels and their condition, including engine oil, coolant, power steering, and automatic transmission fluid where accessible, should be inspected for discolouration or emulsification, and any dashboard warning lights illuminated at key-on should be noted and investigated before purchase, as the MOT test does not cover the majority of electronic system faults on a vehicle of this complexity.
