Martin Vanquish S
5.9L V12
The 2006 Aston Martin Vanquish S is the swan-song edition of Aston's first-generation aluminum-bonded supercar. It packs a 5.9L naturally aspirated V12 making 520 hp, hand-built at the Newport Pagnell factory — a facility with coachbuilding roots stretching back over a century. The Vanquish S was the ultimate expression of that generation, with stiffer suspension, revised throttle mapping, and a 10 hp bump over the standard Vanquish. The automated manual gearbox (called the ASM — Aston Shift Manual) is a single-clutch paddle-shift unit that is both the car's most distinctive feature and its most common headache. It can feel jerky in everyday use and requires specialist knowledge to diagnose and repair. This is not a car for owners who want to drop it at any shop; it needs an Aston-specialist or factory-trained technician. Think of this vehicle as a low-volume British exotic first, a daily driver never. It rewards meticulous, scheduled maintenance and absolutely punishes neglect. Running costs are high by any measure, but ownership of one of the last hand-built Newport Pagnell cars carries real collector significance.

Maintenance schedule
- 1 Every 5,000 miles or 6 months Engine Oil & Filter Change
The V12 runs hot and works hard. Use only the manufacturer-specified full-synthetic grade. Skipping intervals accelerates sludge buildup and chain wear.
- 2 Every 60,000 miles or 72 months Transmission Fluid Change (ASM)
The ASM single-clutch unit is sensitive to fluid degradation. Stale fluid worsens shift quality and accelerates clutch wear. Use only the specified fluid — do not substitute.
- 3 Every 24,000 miles or 24 months Brake Fluid Flush
The high-performance braking system is heat-intensive. Moisture-laden brake fluid lowers boiling point and can cause fade or corrosion in calipers.
- 4 Every 30,000 miles or 36 months Coolant Flush
Aston's aluminum-intensive construction is sensitive to incorrect or degraded coolant. Old coolant becomes acidic and attacks aluminum components and seals.
- 5 Every 50,000 miles or at first sign of rough idle/misfires Intake Valve Carbon Cleaning
Carbon deposits on intake valves are a known issue on this V12. Cleaning restores proper airflow, eliminates misfires, and prevents lean codes.
- 6 Every 10,000 miles or 12 months Tire Rotation
The Vanquish S wears rear tires significantly faster under hard acceleration. Regular rotation extends tire life and maintains balanced handling.
- 7 Every 30,000 miles Spark Plug Inspection & Replacement
With 12 cylinders, plug replacement is labor-intensive but critical. Worn plugs on this engine contribute directly to misfires and lean codes.
- 8 Annually, and before any storage period Battery Condition Test & Tender Use During Storage
The Vanquish S has a significant parasitic draw from its electronics. A weak battery causes electrical gremlins and can corrupt ASM calibration. Use a quality trickle charger during any storage over two weeks.
Always defer to the manufacturer's service manual for warranty-mandated intervals.
Cost of ownership
Annual maintenance
$3,000 – $8,000
Fuel
Premium 91+ octane required. At 12 MPG combined and typical Wisconsin driving, expect $4,000–$6,500/year in fuel alone at current prices.
Insurance
Expect $3,000–$6,000+/year for agreed-value collector car insurance. Standard auto policies often undervalue this car — a specialty insurer is strongly recommended.
This is one of the most expensive-to-own vehicles in the exotic segment. Routine maintenance alone runs $3,000–$8,000 annually at an independent Aston specialist. Any drivetrain repair (ASM clutch, cooling, catalytic converters) can easily hit $3,000–$8,000 per incident. Parts sourcing from the UK adds lead time and cost. Budget a minimum $10,000–$15,000/year all-in for a well-kept, regularly driven example.
Seasonal care
Lake Geneva, WI Winter
- Do NOT drive this car on salted Wisconsin roads. Road salt will corrode the aluminum body panels, undertray, and brake components at an accelerated rate — damage that is extremely expensive to repair.
- Store the vehicle from first snowfall through spring thaw. A climate-controlled garage is strongly preferred to prevent condensation on aluminum and electrical connectors.
- Connect a quality battery tender throughout winter storage. The car's electronics draw power even when off, and a dead battery can cause ASM control module issues.
- Change oil before storage, not after — used oil carries acids that will corrode engine internals during long sit periods.
- Fill the fuel tank and add a fuel stabilizer if storing more than 60 days to prevent varnish in the fuel system.
- Check tire pressure monthly during storage — cold Wisconsin temps cause significant PSI drop in sitting tires.
Summer
- Monitor coolant temperature closely — the V12 generates substantial heat and aging cooling system components (hoses, expansion tank) are prone to failure under summer heat load.
- Check tire pressure after the car has been sitting in the sun — pressure rises with heat and overinflation reduces contact patch and grip.
- Inspect the A/C system before summer use; refrigerant seepage over the storage period is common and the system should be checked for proper charge.
- Wash the undercarriage thoroughly after any spring driving to remove any residual road salt before heat bakes it into seams and crevices.

If you're shopping for one
Red flags
- No specialist service history — a gap of even 12–18 months without documented maintenance is a serious concern on this vehicle
- Any evidence of salt-road driving in a northern state without documented undercarriage protection
- Jerky or unresponsive ASM shifts that can't be resolved with a clutch adaptation procedure — may indicate clutch replacement is imminent
- Collision history of any kind: aluminum body repair requires specialized equipment; improper repairs compromise structural integrity
- Excessive oil consumption or blue smoke on startup, which on this V12 can indicate valve seal or bore wear
- Any indication the car was stored without a battery tender or fuel stabilizer — electrical and fuel system issues can result
What to inspect
- Full ASM transmission service history — a gap in fluid changes or clutch adjustments is a major red flag
- Cooling system condition: inspect hoses, expansion tank, and radiator for cracks, seeps, or discoloration
- Intake valve carbon buildup: ask whether the engine has had a walnut blast or equivalent cleaning
- Catalytic converter health: check for P0420/P0430 codes in stored history — replacement is very expensive
- Body panel fit and finish: look for uneven gaps that may indicate a prior collision repaired without proper aluminum bonding equipment
- Battery health and electrical system: test for parasitic draw issues and scan all modules for stored codes before purchase
