Our Verdict
Exercise extreme caution. This vehicle f
The primary concern for this vehicle is the structural integrity of the chassis. The 2021 MOT failure specifically highlighted excessive corrosion on the nearside and offside rear sills and integral body structures, which typically requires professional welding to rectify. You must verify if these structural repairs were ever completed, as these are costly and safety-critical.
Additionally, the engine management indicator lamp (MIL) was reported as inoperative or malfunctioning. This suggests an electrical or engine fault that could be expensive to diagnose and fix. Given the gap in MOT history since 2021, this vehicle should be treated as a non-runner until a full mechanical inspection is performed.
The 1298cc petrol engine is designed for economy, likely placing it in a lower insurance group and offering reasonable fuel efficiency for a city car. However, as Daihatsu is no longer widely sold in the UK, sourcing specific replacement parts for a 20-year-old model may lead to higher maintenance costs or longer lead times.
Annual costs will include the standard petrol VED tax band for 2004 vehicles and basic insurance. Given the age and recorded condition, maintenance costs are likely to be higher than average to bring the car back to a roadworthy standard.
A thorough inspection of the underbody is essential. Specifically, check the offside and nearside rear sills and inner integral body structures for the corrosion noted in the 2021 MOT. Any signs of fresh, poor-quality welding or hidden filler should be viewed as a red flag.
Check the parking brake efficiency, as it was recorded as being less than 50% of the required value. You should also inspect the front suspension arm and track rod end ball joint dust covers on both sides, which were flagged as severely deteriorated or damaged during its last test.
This silver 2004 Daihatsu Sirion presents a significant risk to buyers. Its last recorded MOT in November 2021 resulted in a failure at 84,534 miles, citing critical issues with chassis corrosion and braking efficiency. With no MOT records for several years, the current roadworthiness of this 1.3L petrol vehicle is unknown.
No aggregate MOT data is available to provide a general reliability trend for the Daihatsu Sirion.
