Expert verdict

Emissions & leaks: 2.0× the national share

Emissions & leaks make up 10.8% of everything recorded on the 2005 Ford Mustang, against 5.5% nationally — 5.3 points above. Suspension is still the single largest share at 23.9%, but at 21.0% nationally that one is ordinary. A smoky diesel or a leaking joint fails on emissions more often than on wear, so ask for a recent emissions printout.

Before your test

Three checks worth doing on a 2005 Mustang

These are not generic tips — they are the faults recorded most often on this exact model, rewritten as things you can check yourself. All three take about ten minutes and cost nothing.

  1. Check the suspension joints 3.8% of tests

    “track rod end ball joint dust cover damaged or deteriorated,”

    With the car parked on level ground, rock the top of each front wheel in and out while someone watches the suspension arm. Clunks, or rubber boots split and greasy, are what testers record here.

  2. Check the lights 2.3% of tests

    “malfunction indicator lamp inoperative or indicates a malfunction”

    Switch everything on and walk round the car: both headlamps on dip and main, every indicator, both brake lights, reverse, fog and the two number-plate lamps. A bulb is a few pounds and a five-minute job.

  3. Check the exhaust and emissions 1.9% of tests

    “catalyst emissions Lambda reading after 2nd fast idle outside specified limits”

    Listen for a blow at idle and have someone rev it gently. Then look at the tailpipe smoke: blue is oil, white when warm is coolant, black is over-fuelling. Any of those and the emissions test is the least of it.

Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.

What it costs to get a 2005 Mustang through its MOT
