Chrysler 300C
The Chrysler 300C brought unapologetic American "gangster" styling to the UK executive car market, offering massive road presence at a fraction of the cost of German rivals. Underpinning its bold exterior is heavily modified, older-generation Mercedes-Benz E-Class running gear, which lends the car a wafty, comfortable ride perfectly suited to motorway cruising. In the UK, the 3.0-litre V6 diesel (sourced from Mercedes) was by far the most popular choice, offering a great blend of torque and reasonable economy, while the petrol V8s remained a rare indulgence. Reliability is generally robust mechanically, though interior plastics and suspension components can show their age. It suits extroverted buyers looking for an imposing, comfortable cruiser with a distinct personality.

Common Faults & Reliability
These are the most common documented problems for the Chrysler 300C, sorted by their typical impact and frequency.
Suspension Bush & Ball Joint Wear
medium severityThe 300C is a very heavy car, and its suspension components (derived from the Mercedes W211) take a beating on UK roads. Ball joints and control arm bushes often last less than 40,000 miles.
Swirl Motor Failure (3.0 CRD)
high severityOil leaks from the turbocharger intake pipe can drip directly onto the swirl flap motor located in the "V" of the engine, causing it to short out and put the car into limp mode.
Inlet Manifold Corrosion (2005–2007 Diesel)
high severityOn early 300C diesels, the inlet manifold can corrode internally and suck plastic fragments into the engine, causing potentially catastrophic damage. Cars built between 2005 and 2007 are most affected.
