As a Melbourne-based car enthusiast with over a decade of diving into the world of JDM vehicles, I’ve had the thrill of owning a Honda S660, a Kei car that lives up to its “Baby NSX” nickname. I imported my vibrant, canary-yellow S660 for AUD 30,000 through Cult and Classic, a trusted JDM importer, and it’s been an exhilarating journey. With its mid-engine layout, rear-wheel drive, and turbocharged 660cc engine, this pint-sized roadster delivers unmatched driving joy in a compact package.

From weaving through Melbourne’s tight laneways to carving up twisty coastal roads, every moment behind the wheel has been unforgettable. In this detailed review, I’m sharing the top 10 reasons why the Honda S660 is a must-buy in 2025, based on my hands-on experience. If you’re chasing a JDM icon that blends style, performance, and exclusivity, read on to discover why the S660 deserves a spot in your garage!

Top 10 Reasons to Buy a Honda S660

1. Exhilarating Go-Kart-Like Handling

The S660’s handling is nothing short of spectacular, thanks to its near-perfect 50/50 weight distribution and featherlight 830 kg curb weight. On twisty backroads near Melbourne, I’ve pushed this car through tight corners, and its razor-sharp steering feels like an extension of my thoughts. The low center of gravity eliminates body roll, making it feel like a go-kart on steroids. Whether navigating sharp hairpins or sweeping curves, the S660 stays planted and predictable, delivering a grin-inducing experience every time. Compared to heavier sports cars, its agility is unmatched, making it a dream for enthusiasts who crave precision and fun.

• 50/50 weight distribution: Ensures balanced handling
• Razor-sharp steering: Responds instantly to inputs
• Center of gravity: Low profile keeps it glued to the road

2. Rare Mid-Engine, Rear-Wheel-Drive Layout

The S660’s mid-engine, rear-wheel-drive configuration is a rarity in the Kei car segment, echoing the layout of the legendary Honda NSX. This setup places the engine behind the driver, optimizing weight distribution for superior dynamics. On Melbourne’s urban streets, I’ve felt the car’s nimble response as it darts through traffic, while on open roads, the rear-wheel drive delivers a playful, engaging feel. Unlike most Kei cars with front-wheel drive, the S660 offers a true sports car experience, making it a standout choice for purists seeking something extraordinary.

• Mid-engine: Enhances balance and agility
• Rear-wheel drive: Provides sporty, engaging dynamics
• Honda NSX: Shares DNA with a JDM legend

3. Slick Six-Speed Manual Transmission

The S660’s six-speed manual transmission is a masterpiece, with short, precise throws that make every shift a delight. During my Sydney-to-Melbourne road trip, the short-throw shifter kept me engaged through long stretches of highway and twisty backroads alike. Each gear change feels mechanical and satisfying, a rarity in modern cars where automatics dominate. Compared to other Kei cars like the Suzuki Jimny, which offers a five-speed manual, the S660’s six gears provide better flexibility, especially at higher revs. For enthusiasts who love the art of manual driving, this gearbox is a major reason to buy.

• Six-speed manual: Rare in Kei cars, highly engaging
• Short-throw shifter: Precise and tactile
• Gear flexibility: Ideal for spirited driving

4. Head-Turning JDM Design

My S660’s canary yellow paint and aggressive styling make it a head-turner wherever I go. Its compact size—smaller than many motorcycles—combined with sporty elements like muscular haunches and a sleek LED reflector bar creates a striking presence. The Modulo wheels (15-inch front, 16-inch rear) wrapped in Yokohama Advan Neova tires give it an NSX-like stance. Driving through Melbourne’s bustling laneways, I’ve had countless strangers snap photos or ask, “What’s that car?” The frameless doors and functional air intakes add to its JDM aesthetic, making it a rolling piece of automotive art that stands out in any crowd.

• Muscular haunches: Surprisingly powerful look
• *LED reflector bar: Modern, stylish rear design
• Modulo wheels: Lightweight, staggered for sporty appeal
• JDM aesthetic: Authentic Japanese design flair

5. Punchy Turbocharged 660cc Engine

The S660’s 660cc 3-cylinder turbo engine delivers 47 kW (63 hp) and 101 Nm of torque, punching above its weight thanks to the car’s lightweight chassis. I clocked 0-100 km/h in ~14.9 seconds on a wet day with a passenger, but the turbocharged kick at 5,500 RPM makes it feel livelier than the numbers suggest. On open roads, I’ve revved it to 7,500 RPM, where the engine sings with enthusiasm. While not a speed demon, the S660’s power-to-weight ratio delivers thrilling acceleration for a Kei car, perfect for spirited drives without overwhelming power.

• 660cc turbo engine: Small but potent
• Turbocharged kick: Peak torque at 5,500 RPM
• Power-to-weight ratio: Lightweight chassis maximizes performance

6. Impressive Fuel Efficiency

Even when driven like an “absolute idiot” on Melbourne’s outskirts, the S660 achieves ~5 L/100 km (19 km/L), making it a fuel-efficient thrill machine. This efficiency is a game-changer for enthusiasts who want to enjoy frequent joyrides without dreading fuel costs. Compared to larger sports cars, the S660’s 660cc engine sips fuel while still delivering smiles. On my long drives, I’ve been amazed at how little fuel it uses, even under hard acceleration, making it an economical choice for weekend adventures.

• Fuel-efficient: ~5 L/100 km under spirited driving
• 660cc engine: Small displacement, big savings

7. Surprisingly Comfortable Ride

Despite its sporty DNA, the S660 offers a compliant suspension that soaks up bumps better than expected. On my Melbourne-to-Sydney road trip, it handled rough roads with ease, keeping me comfortable despite the low ride height. The supportive seats hugged me through corners and stayed cozy for hours, fitting drivers up to 6’2”. The lack of body roll ensures a planted feel, making the S660 more livable than many sports cars, even on extended journeys.

• Compliant suspension: Absorbs bumps well
• Low ride height: Eliminates body roll
• Supportive seats: Comfortable for long drives

8. Extensive JDM Modifications

My S660 is a JDM enthusiast’s dream, loaded with aftermarket upgrades that amplify its character. The Roso Modello exhaust with burnt steel tips delivers a throaty roar, while the HKS blow-off valve adds an iconic “whoosh” on gear changes. A turbo boost gauge (Blu-Tacked on after adhesive failed) and front/rear dash cams add practicality and flair. The Modulo wheels enhance handling and aesthetics. These mods make every drive a sensory experience, though they require permits in Australia due to noise regulations.

• Roso Modello exhaust: Deep, aggressive sound
• HKS blow-off valve: Iconic JDM “whoosh”
• Turbo boost gauge: Monitors performance
• Modulo wheels: Lightweight and stylish

9. Perfect for Urban Adventures

The S660’s compact dimensions make it ideal for navigating Melbourne’s tight laneways and crowded parking lots. It slips into spaces where larger cars can’t, yet the cabin feels spacious for my 5’11” frame. The open-top roadster design, with easy-to-remove soft top, transforms city drives into open-air adventures. On sunny days, I’ve cruised along the coast, feeling the breeze and turning heads. For urban dwellers who love driving, the S660 is a practical yet thrilling choice.

• Compact dimensions: Fits tight urban spaces
• Open-top roadster: Enhances city driving fun

10. Exclusive JDM Ownership Experience

Owning a Japan-exclusive Kei car like the S660 feels like being part of an elite club. Imported through Cult and Classic, my S660 cost AUD 30,000—a fair price for a modified, low-mileage gem. Its exclusivity and NSX-inspired DNA make it a rare find outside Japan. The process of importing, driving on permits, and sourcing parts adds to the adventure. I’m selling mine to fund another JDM project, but the unique ownership experience has been unforgettable.

• Kei car: Japan-exclusive rarity
• Exclusivity: Rare outside Japan
• NSX-inspired DNA: Shares sporty heritage
• Unique ownership: A thrilling JDM journey

The Honda S660 is a JDM masterpiece that combines go-kart-like handling, striking design, and exclusive appeal in a compact package. From its six-speed manual and turbocharged engine to its JDM modifications and fuel efficiency, it’s a car that delivers joy on every drive. Whether I’m weaving through Melbourne’s streets or hitting coastal roads, the S660 never fails to impress. Mine’s headed to Cult and Classic with registration-ready parts for Australia—don’t miss your chance to own this Baby NSX! Have you driven a Kei car or dreamed of owning an S660?
