Honda S500: A Comprehensive Guide

The Honda S500, produced from 1963 to 1964, holds a significant place in automotive history. It represents Honda's first true production automobile, following the limited-production T360 mini-truck. The S500 is a small, open-top sports car designed to showcase Honda's engineering prowess and challenge established European manufacturers. It's a roadster, designed for spirited driving and open-air enjoyment.

Generations

  • First Generation (1963-1964): This is the only generation of the S500. Key features include:
    • High-revving 531 cc DOHC inline-four engine
    • Chain drive to the rear wheels
    • Independent suspension on all four wheels
    • Distinctive styling with a prominent grille and small proportions

Reliability & Common Issues

Owning an S500 requires a deep understanding of vintage vehicle maintenance and a commitment to addressing potential issues. While Honda engineering is generally robust, age and limited availability of parts can present challenges.

Engine

The S500's engine is a marvel of engineering for its time. However, its high-revving nature means wear and tear are common. Key areas of concern include:

  • Valve Train: Frequent oil changes are essential due to the high-revving nature. Valve adjustment is critical and should be done regularly. Worn valve guides and seats are common issues.
  • Carburation: The S500 uses multiple carburetors which require precise tuning. Maintaining proper synchronization is vital for smooth running. Rebuilding kits are available but require expertise.
  • Cooling System: Overheating can be a problem. Ensure the radiator is clean and the thermostat is functioning correctly. Leaks are common in aging hoses and the water pump.
  • Oil Leaks: Expect oil leaks from various seals and gaskets due to age. Regular inspection and timely repairs are necessary.

Drivetrain

The chain-drive system is unique and requires specific attention:

  • Chains and Sprockets: Inspect chains and sprockets for wear and proper lubrication. Replacement chains can be difficult to source, so proper maintenance is paramount.
  • Chain Cases: Check chain cases for leaks. Maintaining the correct oil level is essential for chain lubrication.

Suspension & Brakes

The independent suspension is sophisticated but can suffer from age-related issues:

  • Suspension Bushings: Rubber bushings deteriorate over time, leading to sloppy handling. Replacing them with polyurethane bushings can improve performance and longevity.
  • Brakes: The S500 has drum brakes all around. Inspect brake shoes and cylinders for wear and leaks. Brake fade can be an issue under heavy use.

Body & Chassis

Rust is a significant concern, especially in areas prone to moisture:

  • Rust: Check floors, rocker panels, and wheel arches for rust. Repairing rust can be expensive and time-consuming.
  • Convertible Top: The convertible top is prone to damage and leaks. Replacement tops are available, but installation may require professional assistance.

Driving Experience

Driving an S500 is a unique and engaging experience. The high-revving engine demands to be worked hard, and the handling is nimble and responsive. However, it's not a car for the faint of heart.

Pros:

  • Exhilarating Engine: The engine loves to rev and provides a thrilling soundtrack.
  • Nimble Handling: The small size and independent suspension make it fun to drive on winding roads.
  • Unique and Rare: Owning an S500 is a statement. It's a head-turner and a conversation starter.
  • Direct Driving Experience: The lack of modern conveniences provides a pure and engaging driving experience.

Cons:

  • Limited Power: The engine's small displacement means acceleration is modest by modern standards.
  • Maintenance Intensive: Keeping an S500 running requires significant effort and expertise.
  • Parts Availability: Finding replacement parts can be challenging and expensive.
  • Ride Quality: The ride is firm and can be uncomfortable on rough roads.

Buying Advice

Buying an S500 requires careful research and a thorough inspection. Here's what to consider:

  • Condition is Key: Prioritize a car with minimal rust and a well-maintained engine. A complete and original car is more desirable.
  • Inspect Carefully: Pay close attention to rust, engine condition, and the chain-drive system.
  • Compression Test: Perform a compression test to assess the engine's health.
  • Professional Inspection: Have a qualified mechanic familiar with vintage Hondas inspect the car before you buy it.
  • Paperwork: Look for documented service history.
  • Pricing: Prices vary widely depending on condition. Be prepared to pay a premium for a well-preserved example.
  • Parts Sourcing: Research parts availability and costs before committing to a purchase.

Years to Look For: All S500s are desirable, but those with complete documentation and minimal rust are the most valuable.

What to Avoid: Avoid cars with significant rust damage, major mechanical issues, or missing original parts unless you are prepared for extensive restoration work.

Owning a Honda S500 is a rewarding experience for those who appreciate vintage cars and are willing to invest the time and effort required to maintain them. It's a piece of automotive history that offers a unique and engaging driving experience.
