The Aston Martin DB6: A Comprehensive Guide

The Aston Martin DB6, produced from 1965 to 1970, is a grand tourer that cemented Aston Martin's reputation for elegant styling and high performance. It succeeded the DB5, famously associated with James Bond, and built upon its predecessor's success with improved aerodynamics, more passenger space, and enhanced practicality. Representing the culmination of the "David Brown" era, the DB6 holds a special place in Aston Martin history, blending classic aesthetics with significant engineering advancements.

What Class of Car is the DB6?

The Aston Martin DB6 falls squarely into the category of a grand tourer (GT). This means it's designed for comfortable, high-speed long-distance driving. Characteristics of a GT car like the DB6 include: a powerful engine, refined handling, a comfortable interior, and a stylish exterior. It's a car meant to be both enjoyable to drive and suitable for carrying passengers and luggage on extended journeys.

Generations

While there's only one main DB6 generation, there were notable updates throughout its production run. Here's a breakdown:

  • DB6 (1965-1969): The original DB6 featured a longer wheelbase (increasing rear passenger legroom), a Kamm tail (improving aerodynamics), split front and rear bumpers, and improved oil cooler. The engine was a 4.0-liter inline-six derived from the DB5.
  • DB6 Vantage (1966-1969): Offered a more powerful engine variant with triple Weber carburetors, producing around 325 bhp. Distinguished visually by "Vantage" badging.
  • DB6 Mark II (1969-1970): Introduced minor improvements, including flared wheel arches (to accommodate wider tires), and optional power steering. It also used the DBS rear lights instead of the DB6 lights. Mechanically, it was largely the same as the earlier DB6 models.
  • DB6 Volante (1966-1970): The convertible version of the DB6. These are significantly rarer and more valuable than the fixed-head coupes. Shared mechanical components and updates with the standard DB6 coupe.

Reliability & Common Issues

Owning a classic Aston Martin DB6 requires careful attention to maintenance. Here are some key areas of concern:

  • Engine: The 4.0-liter inline-six is generally robust, but regular servicing is crucial. Potential issues include oil leaks (especially from the rear main seal), worn camshafts (especially in early models), and carburetor problems (particularly with the Weber setup on the Vantage). Ensure the engine starts easily and maintains good oil pressure. Look for blue smoke indicating worn valve guides or piston rings.
  • Gearbox: The standard ZF five-speed manual gearbox (or optional automatic) is generally reliable, but listen for whining noises or difficulty shifting, which could indicate worn synchros or bearings. Automatic transmissions should shift smoothly without jerking.
  • Bodywork: Rust is a major concern, especially in the sills, wheel arches, and around the lights. The aluminum body panels are susceptible to corrosion, and repairs can be costly. Carefully inspect the chassis for rust, particularly where it meets the body. Accurate panel gaps and consistent paint are indicators of a well-maintained or properly restored car.
  • Suspension & Brakes: Check the suspension for worn bushings and shock absorbers. The Girling braking system should be in good working order, but ensure the brakes are not spongy or pulling to one side. The handbrake mechanism can also be prone to issues.
  • Electrics: Lucas electrical systems are notorious for their quirks. Check all lights, gauges, and switches are functioning correctly. Wiring harnesses can become brittle with age, leading to shorts and other problems.
  • Interior: The leather upholstery and wood trim require regular conditioning. Check for cracks, tears, and water damage. The original Connolly leather can be expensive to replace.
  • Kamm Tail Stress Cracks: The area where the Kamm tail meets the rear wings is a known stress point and can exhibit cracking. Look closely for repairs.
  • Fuel System: The fuel tank can rust internally, and fuel lines can degrade over time, leading to leaks. The fuel pump should operate quietly and efficiently.

Pro Tip: A pre-purchase inspection by a qualified Aston Martin specialist is highly recommended. They can identify potential issues that might not be apparent to the untrained eye.

Driving Experience

The DB6 offers a uniquely rewarding driving experience, blending classic GT character with surprising performance.

Pros:

  • Effortless Performance: The 4.0-liter engine provides ample power for cruising and overtaking. The Vantage models offer a noticeable performance increase.
  • Comfortable Ride: The long wheelbase and well-tuned suspension provide a comfortable ride, even on long journeys.
  • Elegant Styling: The DB6 is undeniably beautiful, with timeless lines that continue to turn heads.
  • Engaging Driving Experience: While not a sports car, the DB6 offers a connected and engaging driving experience. The steering is direct, and the handling is surprisingly nimble for a car of its size.
  • Iconic Status: Owning a DB6 is owning a piece of automotive history. It's a car that commands respect and admiration.

Cons:

  • Maintenance Costs: Classic Aston Martins can be expensive to maintain. Parts can be difficult to find and costly, and specialized knowledge is required for repairs.
  • Reliability Issues: As with any classic car, the DB6 is prone to breakdowns and requires regular maintenance.
  • Limited Practicality: While the DB6 is a GT car, it's still relatively compact. Rear passenger space is limited, and the trunk is not particularly large.
  • Fuel Economy: Expect poor fuel economy, especially with the Vantage models.
  • Heat: In warmer climates, the interior can get quite hot as the air-conditioning system (if equipped) may not be as effective as modern systems.

Buying Advice

Purchasing an Aston Martin DB6 requires careful research and consideration. Here's some advice to help you make an informed decision:

Years to Look For:

  • DB6 Mark II (1969-1970): While relatively rare, the Mark II models often incorporate minor improvements and refinements, such as the flared wheel arches which can allow for more modern tire fitment and DBS rear lights.
  • DB6 Volante (all years): These are the most desirable and valuable, offering open-top motoring.
  • Well-Documented Examples: Regardless of the year, look for cars with a comprehensive service history and evidence of regular maintenance.

Years to Potentially Avoid (or Approach with Caution):

  • Early DB6 (1965-1966): These models may have some early production quirks. Ensure any potential issues have been addressed by previous owners.
  • Cars with Significant Rust: Avoid cars with extensive rust damage, as repairs can be very expensive.
  • Cars with Poorly Executed Restorations: A poorly restored car can be a money pit. Look for cars restored by reputable specialists.
  • Be wary of 'barn finds' that have been sitting for extended periods: These will often require extensive and costly mechanical work.

Key Considerations:

  • Budget: DB6 prices vary significantly depending on condition, originality, and history. Set a realistic budget that includes purchase price, maintenance, and potential repairs.
  • Condition: Prioritize condition over originality. A well-maintained car is always preferable to an unrestored original.
  • Originality: While originality is desirable, modifications that improve reliability or performance (such as electronic ignition or modern braking systems) can be beneficial.
  • Documentation: A comprehensive service history is essential. Look for records of regular maintenance, repairs, and restorations.
  • Expert Inspection: Have the car inspected by a qualified Aston Martin specialist before making a purchase.
  • Don't Rush: Take your time and carefully evaluate multiple cars before making a decision. Finding the right DB6 is worth the effort.

The Aston Martin DB6 is a truly special car that offers a unique blend of classic style, performance, and character. While owning one requires commitment and careful maintenance, the rewards of driving and owning such an iconic automobile are well worth the effort.
