Why Choose a Used Mazda 3?

Its reputation for reliability also makes it a smart choice for a used car purchase.

Popular Mazda 3 Models and Variants

The Mazda 3 has been produced across several generations, with key models and their popular variants to consider:

• Third Generation (2013-2018): Available as a hatchback (BM/BN) and saloon, often featuring 1.5L and 2.0L Skyactiv-G petrol engines, or a 2.2L Skyactiv-D diesel. Trim levels like SE, SE-L, Sport Nav offered varying levels of equipment and style.
• Fourth Generation (2019-Present): Introduced with a more evolved design and technology. Petrol engines include the 1.5L Skyactiv-G and the innovative 2.0L Skyactiv-X with mild-hybrid technology. Diesel options are less common. Trims like SE-L, Sport, and GT Sport aim to cater to different preferences.

What to Look for When Buying

When inspecting a used Mazda 3, pay attention to the following:

• Exterior: Inspect for dents, scratches, and rust, especially around wheel arches, sills, and door edges. Check alloy wheels for kerb damage.
• Interior: Look for wear on seats (particularly the driver's bolstering), steering wheel, and gear knob. Test all electronic features – windows, mirrors, air conditioning, and infotainment system.
• Engine: Listen for any unusual noises, smoke from the exhaust, or warning lights on the dashboard. Check the service history for regular maintenance.
• Tyres: Ensure they have adequate tread depth and are evenly worn.
• Test Drive: Pay attention to how the car drives, brakes, and handles. Does the clutch feel smooth? Are there any strange noises from suspension or drivetrain?

Mazda 3 Running Costs

The Mazda 3 generally offers reasonable running costs, especially with the Skyactiv petrol engines which are favouring efficiency. Diesel variants can offer better MPG on long journeys but may incur higher maintenance costs in the long run, particularly for DPF-related issues.

• Fuel: MPG figures vary by engine and driving style, but expect anything from 40-60 MPG for petrol and 50-70 MPG for diesel on average.
• Insurance: As a popular model, insurance costs are generally moderate, but will depend on your individual circumstances and the specific variant.
• Road Tax (VED): For vehicles registered before April 2017, tax is based on CO2 emissions. For newer vehicles (post-April 2017), a flat annual rate applies (£190 for 2023/2024), with potential surcharges for cars over £40,000 list price when new.
• Servicing: Mazda servicing is typically competitive. Many independent garages also cater to the marque.

Common Issues and Things to Watch Out For

While generally reliable, some minor issues have been reported on certain Mazda 3 models:

• Infotainment System Glitches: Some older systems could occasionally freeze or be slow to respond. Ensure it's up-to-date.
• Cobwebbing in Headlights: Primarily an aesthetic issue on older models, where a fine cobweb-like pattern can appear inside the headlight lenses.
• Diesel Particulate Filter (DPF): Diesel models, especially if primarily used for short, urban journeys, can be prone to DPF regeneration issues. Ensure the car has been driven appropriately.
• Minor Electrical Gremlins: As with any car, sporadic electrical faults can occur. A full pre-purchase inspection can help identify these.
