Summary Verdict
The 2004 Aston Martin Vanquish, while a desirable supercar, exhibits some common reliability concerns associated with high-performance vehicles of its age. The V12 engine, though powerful, can experience issues with ignition coils and cooling system components. The ‘Touchtronic’ transmission, while advanced for its time, may require attention to its torque converter or hydraulic control unit. Electrical gremlins, particularly with the CEM and infotainment system, are also noted. Suspension components, especially adaptive dampers, can develop leaks. Owners should be prepared for potentially significant repair costs, especially for powertrain and electrical issues. Regular maintenance and prompt attention to early symptoms are crucial for preserving the Vanquish’s performance and value.
