Supercar beauty, attainable grand tourer
The DB7 (1994-2004) was the car that saved Aston Martin, outselling all previous models combined. The early supercharged straight-six models start from around £30,000, while the later V12 Vantage commands £40,000-£60,000. It offers genuine Aston Martin grand touring for a fraction of the cost of a modern DB11, but running costs remain firmly in the supercar bracket and neglected examples become money pits.
We track 5 known issues across the Aston Martin DB7 range, including 1 rated as safety-critical. Knowing which variants and configurations to approach with caution can save you from expensive surprises after purchase.

DB7-I6 (1994–1999) — Engine options included the 3.2 Supercharged I6. Our database flags 4 known issues on this generation, 1 of which are rated as safety-critical. The most significant concern is Wheel bearing excessive play (£200–£400 to address).
DB7-V12 (1999–2004) — Engine options included the 5.9 V12. Our database flags 5 known issues on this generation, 1 of which are rated as safety-critical. The most significant concern is Wheel bearing excessive play (£200–£400 to address).
Both I6 and V12 models show wheel bearing failures at up to 44.6 times the national fleet average, with the trend worsening over time. This affects all four corners and all mileage bands from 20,000 miles upward, suggesting either inadequate bearing specification for the vehicle weight or manufacturing quality issues. The high failure rate across such a wide mileage range indicates this is a fundamental design problem rather than normal wear.
Wheel bearing collapse can cause complete loss of wheel control and potential wheel detachment. The vehicle should not be driven with confirmed bearing failure. Replacement typically requires specialist hub pullers and precise torque settings critical for safety.
Listen for knocking, clunking or rattling over bumps during the test drive. Inspect the underside for corroded or cracked suspension components. Check the MOT history for suspension-related advisories, which often predict future failures.
The 5-speed automatic transmission fitted to V12 models uses a chain drive system that shows premature wear patterns significantly earlier than typical automatic transmissions. MOT data shows transmission failures at 178.3 times the national fleet average, with peak failures occurring between 20,000-40,000 miles. This suggests an inherent design weakness rather than normal wear. The transmission was sourced from Mercedes-Benz but appears inadequately matched to the V12's torque output.
Chain failure requires transmission removal and rebuild, typically costing £3,000-£6,000 for parts and labour. The car may experience sudden loss of drive without warning. Continued driving with a failing chain risks complete transmission destruction and potential damage to the torque converter.
Test the automatic gearbox extensively in slow traffic, car parks and on hill starts. Feel for any juddering, hesitation or clunking during gear changes. Try repeated low-speed manoeuvres as this is where problems are most apparent.
This suggests multiple leak points from engine gaskets, seals, and connections. The V12 shows particularly high leak rates at low mileages, indicating manufacturing or design issues rather than age-related deterioration.
Severe fluid leaks can cause environmental damage and present fire hazards if oil contacts hot exhaust components. Oil leaks lead to engine damage if levels drop critically. Brake or power steering fluid leaks affect vehicle control and safety.
Check the oil level before the engine is started. Ask the seller how often they top up the oil between services. After a test drive, check the level again and look behind the car for blue or grey exhaust smoke under acceleration.
Both models show spring failures at up to 8.7 times the national fleet average, with the trend worsening across all affected mileage bands. The high failure rate suggests either inadequate spring specification for vehicle weight or manufacturing quality issues. Spring failures can occur as early as 20,000 miles, which is extremely unusual for coil springs on any vehicle.
Fractured springs can cause sudden loss of ride height, potential tyre contact with wheel arches, and dangerous handling characteristics. A completely failed spring can damage brake lines, suspension arms, and other components. The vehicle should not be driven with confirmed spring failure.
Listen for knocking, clunking or rattling over bumps during the test drive. Inspect the underside for corroded or cracked suspension components. Check the MOT history for suspension-related advisories, which often predict future failures.
Both models show suspension bush and joint wear at up to 8.8 times the national fleet average, with failures occurring from very low mileages. The trend is worsening and affects cars with less than 20,000 miles, suggesting either inadequate component specification or manufacturing issues. This appears to affect multiple suspension components rather than a single weak point.
Worn suspension components affect handling precision and tyre life. While not immediately dangerous, multiple component failures can compromise vehicle stability and require expensive simultaneous replacement of several parts.
Listen for knocking, clunking or rattling over bumps during the test drive. Inspect the underside for corroded or cracked suspension components. Check the MOT history for suspension-related advisories, which often predict future failures.

Based on 12k real DVSA MOT tests, the Aston Martin DB7 fails more often than average on several items. The biggest outlier is transmission joint, belt or chain worn at 178x the fleet average, followed by power steering fault (25x).
When viewing a specific car, check its MOT history for recurring advisories in these categories. See the full Aston Martin DB7 MOT failure breakdown for data at every mileage point.
Routine servicing (oil and filter change every 6k miles) typically costs £150–£250 at an independent garage.

The Aston Martin DB7 has some well-documented weak points, including 1 safety-critical issue that demand careful checking. The right example, properly maintained, can still be a sound purchase — but cutting corners on the pre-purchase inspection is not advisable. The V12 Vantage from 1999 onwards is the more desirable and characterful car. Late-production 2002-2004 GT and GTA models had the most refinements and best build quality. For the i6, later 1997-1999 cars with the improved 3.2 supercharged engine are preferable to early examples. Full service history from a marque specialist is essential regardless of year.
