501 MOT tests on the 2004 Mazda Premacy are in this dataset, and 66.5% of them passed. That is 5.8 percentage points worse than all cars of a similar age, which fail at 27.7%. Failures cluster in suspension, lighting & signalling and brakes.
What the MOT record shows
One area stands out: suspension, recorded in 20.2% of tests against 14.8% for the next-worst category.

What to check before buying a 2004 Premacy
The failure pattern for this year is specific enough to inspect against: suspension accounted for 20.2% of tests. Start there.
- Suspension (20.2% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
- Lighting & signalling (14.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (14.6% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
