Mazda 6
The Mazda 6 (2012-2023, heavily updated over its life) is the handsome, keen-driving alternative to the obvious rep saloons and estates - a car that always felt a class above its price. UK examples are Skyactiv petrols and the excellent 2.2 diesel. Sharp to drive, smartly styled inside and out, and now discontinued, it's a used bargain for buyers who want some flair with their family mileage.
How these figures are sourced — the valuation is anchored to a researched used-market price for this model (AutoTrader median, 2023 at 30k miles). Reliability, mileage and variant data are real DVSA MOT records. Dimensions, tyre sizes and costs, servicing figures and the insurance group are segment-level estimates rather than sourced per car, and are being replaced model by model.

The short version
Forecourt score
Value 40 · Reliability 77 · Insurance 47 · catalogue percentiles
The Mazda 6 holds its value about averagely and costs about average to run. Its MOT-based reliability is excellent — an MOT score of 85/100, ahead of 25% of the cars we track. On three-year value retention it ranks better than 40% of models.
The Forecourt score blends how this car ranks against the catalogue on value retention, reliability and insurance cost (weighted 40/40/20) — the from-new ownership picture. Higher is better; running cost is not yet folded in.

What it costs to own
Based on the 2023 car with 33,135 miles you entered above — worth about £17,150 today — here is the cost of owning it for the next 5 years, at roughly 11,045 miles a year.

Best age to buy — around 3 years
A 3-year-old example loses roughly £2,600 a year — 57% less than the £6,050 a one-year-old sheds. The steepest drop is behind it.
Uses current UK pump and home-charging prices (DESNZ weekly), typical-driver insurance and manufacturer service intervals. "Fuel per mile" is just the energy input — so an EV at ~9p and a diesel at ~22p make running-cost comparison direct. A guide; your own costs will vary.

How we estimate this
Indicative annual comprehensive premium estimates. The 'Typical' figure represents an average UK driver in each age band; Lower and Higher risk show the realistic spread driven by factors UK insurers legitimately price on (postcode, occupation, claims history, NCB, voluntary excess, modifications). Based on 10,000 miles/yr, £250 voluntary excess, and the no-claims bonus selected above. Always get individual quotes before buying.

"Parts low/medium/high" indicates how easy the replacement part is to source — discontinued or specialist parts mean longer workshop time and bigger bills.
Safety rating
Euro NCAP's independent crash-test rating for the Mazda 6, from its 2018 assessment.
The passenger compartment of the Mazda 6 remained stable in the frontal offset test.
Independent crash-test data from Euro NCAP. Star ratings reflect the test protocol of the year shown — newer protocols are stricter, so a 5-star from 2024 represents a higher bar than a 5-star from 2014. Euro NCAP ratings run for six years from publication; a lapsed rating means the protocol has moved on, not that the car performs any worse than it did on test.
MOT outlook
How this model fares at its MOT as it ages — from 1,941,143 real DVSA test records.
MOT pass rate by age
A 3-year-old 6 passes its MOT 85.8% of the time; by 24 years that has slipped to 81.5%. The y-axis is zoomed to this model’s range so the trend is readable.
Longevity
From 3,465 vehicles registered in 2018.
Survival by registration year
Each point is one registration cohort. Older cars on the left, newer on the right. A flatter line means the model holds up over time; a steep drop means cohorts disappear from UK roads faster.

What fails at the first MOT
The defect categories a 6 registered 2018–2023 fails on at its first MOT, from 11,300 first tests. Every car here is the same age and the same generation, so these are the faults that show up first - not the wear a high-mileage older example collects.

Things owners say
- 01The 2.2 Skyactiv-D diesel is strong and economical but needs regular motorway runs to keep the DPF healthy.
- 02Avoid short-trip-only diesels; the petrols suit lower-mileage town and suburban use better.
- 03Genuinely good to drive and well-built - one of the more satisfying used saloons and estates at the money.
Safety recalls
Manufacturers occasionally issue safety recalls to fix a fault free of charge. You can check whether the Mazda 6, or your exact vehicle, has any outstanding recalls on the official DVSA service.
Check on GOV.UKOpens the Driver & Vehicle Standards Agency recall checker. Choose the make, model and year of manufacture — no registration needed.
Theft risk
A general indicator from UK 2025 theft data and this car’s characteristics — not a prediction for any one vehicle.
Whole-car theft
Around average
Theft risk is around the UK average. Like most modern cars it has keyless entry, so relay theft is the method to guard against.
Parts theft
Higher
Hybrid versions are a catalytic-converter target — a hybrid cat is rich in precious metals and can be cut out in about a minute.
Worth doing
- Keep keys in a Faraday pouch and away from the front door to block relay attacks.
- A catalytic-converter guard or forensic marking makes a hybrid far less appealing to cut.
Clean-air zones
Whether driving a Mazda 6 into a UK clean-air zone will cost you anything. Rules use the same Euro standard across most zones — petrol from 2006 and diesel from 2015 onwards are exempt; pure electric is always exempt.
Charging zones for cars
| City | Area | Daily charge | Likely outcome |
|---|---|---|---|
| London | All of Greater London (within the M25) | £12.50 | Likely exempt Diesel from September 2015 meets Euro 6. |

| Bristol | City centre and part of the Portway | £9.00 | Likely exempt Diesel from September 2015 meets Euro 6. |

Servicing & the dealer network
How well-supported Mazda is across the UK — a practical read on how easy servicing, parts and warranty work will be to find.
Franchised UK dealers
~120
Large network
Mass-market
Network size relative to the UK's largest (Mazda is 2.7% of all franchised outlets)
Servicing, parts and warranty work are easy to find UK-wide, and most independent garages know the brand well — which keeps maintenance competitive.
For context, the UK has roughly 4,500 franchised car-dealer outlets in total, plus about 15,500 independent garages.
Approximate figures, curated from public UK industry sources (NFDA, Car Dealer Magazine). Franchised networks shrink year on year — these indicate network size, not an exact count.

Common questions
Mazda 6, answered from the data
- Is the Mazda 6 reliable?
- The Mazda 6 scores 85/100 on Forecourt's MOT-based reliability measure, ahead of 25% of the cars we track. That score uses first-MOT pass rate and defect rate for cars registered 2018 onward (11,300 first tests), with cohort survival — high confidence.
- How much does a used Mazda 6 cost?
- A 2023 Mazda 6 with around 33,135 miles is worth roughly £17,150 today (typical range £15,400–£18,900). Dealer forecourt prices sit higher and part-exchange offers lower; newer or lower-mileage examples cost more.
- How quickly does the Mazda 6 depreciate?
- A new Mazda 6 typically loses about 43% of its value over the first three years, then depreciates more slowly. Buying at three to five years old avoids the steepest part of the curve.
- What insurance group is the Mazda 6?
- The Mazda 6 sits in insurance group 24 of 50 — the middle of the scale. Exact premiums depend on the trim (some versions sit a few groups higher or lower), your age, postcode and no-claims history.
- What goes wrong on a used Mazda 6?
- The parts most often recorded at MOT on the Mazda 6 are: brakes (typically around over 100k miles, £150-£500 to put right); tyres & wheels (typically around over 100k miles, £80-£500 to put right); suspension (typically around over 100k miles, £150-£450 to put right). A full service history and a recent MOT with no advisories are the best protection.
- What does the Mazda 6 cost to run?
- Expect around 42 mpg combined on the 2.0 Skyactiv-G 145, £200 a year in road tax, about £185 for a standard annual service. The full cost-of-ownership table above breaks this down per year and per mile for the exact year and mileage you choose.
- Is the Mazda 6 ULEZ compliant?
- Whether a Mazda 6 is ULEZ compliant depends on its engine and registration date: petrol from 2006 and diesel from September 2015 generally qualify, and electric versions are always exempt.
- How many Mazda 6s are on UK roads?
- About 53,165 Mazda 6s are currently taxed and on the road in the UK, from DfT vehicle-licensing data.
