Credov's researched list of the 2 faults the Mini JCW (R50/R53) is known for (2001–2006), 1 of them serious or costly. Each one says what to look for when you check the car, so you can spot it before you buy. Not every car has these faults: they are the ones worth checking on this model.
What to look for: On the test drive, do several slow parking turns and feel for the steering suddenly going heavy.
Why it matters: The steering can go heavy without warning, often mid-manoeuvre; a new fan is a cheap fix but a replacement pump is the usual cure once it starts.
What to look for: Run each window up and down twice and watch for one that drops back, sticks or goes up crooked.
Why it matters: A failed regulator can leave a window stuck down or unable to seal, letting rain in and risking the glass itself, and on the Convertible a weak regulator can stop the roof opening or closing properly.
