Car Model Guide/ Mazda/ 6/ GH/ 2.0

2.0 MZR20

A plain chain-driven petrol four with nothing clever about it, which is the point. No turbo and no direct injection means none of the bills that define the diesels in this range.

Overview

The 2.0 is the MZR20 petrol version of the Mazda 6 hatchback (GH), sold 2007–2012 with 147 PS and manual or automatic. Manageable at level 2. A simple chain-driven petrol with no expensive failure of its own, so corrosion is the thing that ends these cars. 1 failure modes are recorded against its engine, gearbox, chassis and shared components, one of which is a walk-away item without documented proof. Prices on this page are illustrative placeholders rather than a sourced market sample. See the methodology for how the bands are derived.

Known issues, ranked by expected cost

Faults recorded against this engine, its components and its chassis, ranked by likelihood × repair cost. Costs are indicative ranges with a stated labour basis.

Corrosion at the arches, sills and boot floor6 platform€300–€2,000

Bubbling paint along the rear arches and sills, and scaling or perforation in the boot floor and around the rear suspension mounts. This generation's corrosion protection doesn't match the reputation the make carries, and cars in salted climates suffer early. It's the fault that ends these cars, because the mechanicals usually outlast the body.

Check: Put it on a ramp and look at the arches, the sills and the boot floor in good light before you look at anything else. Walk away from perforation rather than negotiating on it.

Mileage and servicing

What the odometer does and doesn't tell you here, plus the service items whose neglect causes the expensive failures above.

Look at the arches and sills before the odometer, because rust decides these cars and mileage does not.

Engine oil Simple insurance on a simple engine	on time	€70–110

🇺🇸 United StatesNot sold2.0 MZR20 was never a US-market car

What that meansNo US band exists to compare. Any car you find there's a private import, parts and specialist knowledge are thinner, and the price says more about import cost than about the market.

US figures are the EU band converted at a stated rate. No US market differential is modelled: we hold no sourced US asking prices, and inventing one would be worse than saying so. What the comparison does show for real is availability. Most of this range was never sold in the US.

Buyer notes

Our judgement, kept separate from the records it's built on.

Our read, not a record

The 2.0 MZR is a plain, chain-driven petrol four and that's exactly what you want here, because it avoids everything that goes wrong with the diesels. It gives the car enough pace to enjoy a chassis that's the best in its class. The thing that will end this car is corrosion rather than mechanical failure, so the inspection belongs underneath it. Find a rust-free one and it's a genuinely rewarding thing to own for very little money.

Everything above this line comes from the issue and specification records. This paragraph is our judgement on top of them. See how we reach it.
