Vehicle Value Check
Vehicle Value Check
A typical older Mazda 6 petrol of relevant age is worth approximately £1,000-£4,000 depending on mileage and condition . The replacement-to-value guidance is: - Vehicle worth under ~£1,500: scrap threshold - replacement may not be cost-effective - Vehicle worth ~£1,500-£3,000: evaluate both; used engine may be better value - Vehicle worth ~£3,000+: replacement usually cost-effective
Our Recommendation
Our Recommendation
The MZR petrol engines are robust, and most 'engine failure' cases are actually minor ignition system issues. Start with spark plugs and coil pack diagnosis before considering replacement. A full ignition refresh costs £250-£450 - a fraction of a replacement engine.

Question 2What are the common problems with the Mazda 6 petrol engines-

If the car is in good condition, well-maintained, and you intend to keep it for 2+ years, replacement is often worthwhile. If vehicle value is under £1,500, evaluate scrap value first.
