Expert verdict
Suspension: 2.0× the national share
Suspension accounts for 42.5% of everything recorded on the 2004 Jeep Wrangler Extreme, against 21.0% nationally — 21.5 points above. Ask for the front and rear suspension to be checked on a ramp before you buy — worn bushes and broken springs are cheap to look at and expensive to discover at test time.
- Beats its own age and mileage. Once you allow for how old and how far these cars have been driven, the expected pass rate is 72.2% and this one manages 85.6% — 13.4 points ahead of what its age and mileage predict.
- Failures here tend to be cheap ones. 79% of the repairs this model fails on cost under £30 in parts. The pass rate matters less than what a bad afternoon at the test centre actually costs you.

Before your test
Three checks worth doing on a 2004 Wrangler Extreme
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.
-
Check the wipers and washers 3.1% of tests
“wipers blade defective”
Run the wipers with the screen wet: they should clear it in one sweep without smearing or juddering. Top the washer bottle up and check both jets hit the screen.
-
Check the lights 2.1% of tests
“headlamp not working on dipped beam”
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.
-
Check the suspension joints 1.0% of tests
“ball joint dust cover severely 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.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.
