The DB9 is the car that saved Aston Martin as an independent company and, arguably, saved it as a brand with cultural relevance. It arrived in 2004 and demonstrated that the VH platform was capable of producing something genuinely beautiful. The 6.0 litre V12, the aluminium body, the interior. The DB9 got attention that its predecessor, the DB7, had never quite managed.
It remained in production in various evolutions until 2016. Over that span, the car became more refined and the production quality improved. This matters for buyers because the range of the DB9's production is significant.
The VH platform: what it means for reliability
The VH aluminium platform is the engineering foundation of the DB9. It is a solid platform with one significant complexity: everything it produces is expensive to repair.
Aluminium construction requires specialist skills and tooling. Panel repairs that would cost $500 to $1,500 on a steel-bodied car cost $3,000 to $8,000 on a DB9. Structural repairs require a shop equipped for aluminium work, which eliminates most general bodyshops.
This is a reason to be meticulous about inspecting the car's body before purchase and ensuring any existing damage is either repaired by a specialist before the sale, or priced accurately into your offer.
The Touchtronic transmission
Most DB9s you encounter will have the Touchtronic automated manual. The Touchtronic is a ZF-based unit that, in early versions, had reliability concerns. The actuators that control the gear selection can fail, resulting in the transmission becoming stuck or refusing to engage. Replacement or rebuild is $4,000 to $8,000.
Later DB9s from 2010 onward with updated Touchtronic 2 units are significantly more reliable. If you are considering an early car, ask about transmission service history specifically.
Cooling system maintenance
The 6.0 litre V12 runs hot and the cooling system is a maintenance priority. Coolant hoses, the expansion tank, and the thermostat housing should all have been addressed on any high-mileage example. Ask about coolant system service specifically.
Service history standard
The DB9 requires specialist servicing. A full Aston Martin dealer service history is the gold standard. A documented history with a reputable independent Aston specialist is also acceptable. Gap-filled histories are a problem because you cannot know what has been deferred.
Major service intervals are significant events. A DB9 approaching a major service interval has several thousand dollars of scheduled maintenance ahead of it. Factor this into your offer.
What a good DB9 costs
Clean early DB9 coupes with full service history and no significant known issues are trading at $65,000 to $90,000. Mid-production 2007 to 2010 cars are at a modest premium. Later DB9 GTs and Volante variants trade at $80,000 to $120,000. Manual gearbox examples command a significant premium.
