8 red flags on a used car test drive

One: a warm engine when you arrive. A pre-warmed car hides cold-start rattles, smoke and rough idle — insist on a genuinely cold start. Two: any dashboard warning light that is missing during the bulb check at key-on, which is the classic sign of a removed bulb or a disabled indicator.

Three: uneven panel gaps or paint that differs subtly in texture or metallic flake between adjacent panels. Four: a steering wheel that is not centred while the car tracks straight, pointing at alignment or, worse, unrepaired collision geometry. Five: brake pedal that sinks slowly under steady pressure, indicating a master cylinder leaking internally.

Six: an automatic transmission that hunts, flares between gears or clunks into engagement. Seven: smells — sweet coolant, burnt oil, or the musty note of water intrusion under the carpet, which in Los Angeles usually means a leaking seal or plugged drain rather than flood history, but needs finding either way. Eight: tyres of four different brands or wildly different wear across an axle.

None of these is automatically disqualifying; each is a question to be answered before money changes hands. The test drive's job is to generate that list. A pre-purchase inspection on a lift is what answers it — and it is the only twenty minutes in a used car purchase that reliably pays for itself.
