The timeless rivalry between the NA (Mark 1) and NB (Mark 2) Miata has divided enthusiasts for decades. These two generations of the world’s most beloved roadster share a common DNA of lightweight design and engaging driving dynamics, yet each offers its own distinct experience. While the NA boasts iconic pop-up headlights and a raw, visceral connection to the road, the NB brings modern refinements and sharper performance to the table. This article explores their driving dynamics, design, features, performance potential, and value to help you decide which Miata deserves your attention.

Driving Dynamics

The NA Miata is celebrated for its lightweight construction and pure, “visceral” driving experience. Its handling is approachable and secure, making it an ideal choice for those new to sports cars. Early models are powered by a 1.6L engine producing 116 horsepower, while later models upgraded to a 1.8L engine offering a modest 128 horsepower. However, some drivers feel the NA’s grip-focused suspension can be too planted, leaving it slightly underpowered and less playful than expected. Despite these drawbacks, its simplicity and analog nature deliver a classic driving charm.

On the other hand, the NB Miata takes the NA’s winning formula and refines it further. With improved chassis rigidity, additional bracing, and more tactile steering, the NB offers sharper handling and a more agile driving feel. Powered by a 1.8L engine producing up to 140 horsepower, the NB has more usable power for spirited driving. It also boasts better weight distribution and advanced features like a limited-slip differential in certain trims. While slightly heavier at 2,300 lbs., the NB’s balance and modern setup make it the more confident choice for twisty roads and spirited drives.

Design and Styling

The NA Miata’s design has stood the test of time. Its pop-up headlights remain a beloved feature, evoking 1980s nostalgia and contributing to its iconic status. The NA’s slightly larger interior offers a more spacious cabin, but its simple design feels dated by today’s standards. Its exterior, while timeless, lacks the aerodynamic refinement seen in later generations.

In contrast, the NB Miata features a sleeker and more contemporary design. Fixed headlights replace the NA’s pop-ups, offering improved aerodynamics and modern styling. Later NB2 models (2001–2005) further refined the look with sharper headlights and updated bumpers, giving the car a more aggressive edge. Inside, the NB’s cabin is cleaner and more ergonomic, with optional leather upholstery and better soundproofing for a more comfortable driving experience. While the NB sacrifices some of the NA’s playful charm, it makes up for it with a polished aesthetic and improved practicality.

Features and Practicality

The NA Miata focuses on simplicity and driving purity. Its pop-up headlights and lightweight build reflect a dedication to unfiltered driving joy. The suspension setup is forgiving enough for daily driving, and the NA’s design prioritizes fun over frills. However, it lacks modern conveniences, with early models featuring a plastic rear window that’s prone to damage and minimal safety features such as no airbags in early production years.

The NB Miata addresses these shortcomings with a host of practical upgrades. Most models include a glass rear window with a defroster, significantly improving visibility and durability. Safety features like airbags and a stronger chassis make the NB a safer option, while optional luxury packages introduce leather seats and Bose sound systems for added comfort. The NB also offers a 6-speed gearbox in later models, catering to enthusiasts seeking greater control and performance. While the NB’s interior is slightly smaller, its modern amenities and improved build quality make it a more practical roadster overall.

Performance and Aftermarket Support

The NA Miata is a favorite among enthusiasts for its tunability and straightforward design. Its early OBD-I electronics make it particularly suited for forced induction setups like turbochargers or superchargers. The aftermarket community for the NA is vast, offering a wide array of parts for engine swaps, suspension upgrades, and visual modifications. The pop-up headlights remain a fan-favorite styling point, further fueling the NA’s customization potential.

Similarly, the NB Miata enjoys strong aftermarket support. Many parts are interchangeable with the NA, making it easy to find upgrades like coilovers, roll cages, and exhaust systems. However, the NB’s OBD-II electronics introduce slight limitations for extreme power builds. Despite this, the NB offers a refined driving experience right out of the box, appealing to those who want a balance of modern comfort and classic Miata DNA.

Value and Market Trends

The NA Miata’s cult status has led to an increase in value over the years. As a classic roadster, it’s becoming less affordable for new enthusiasts, with clean examples ranging from $5,000 to $10,000 or more. Special editions or rare trims often command even higher prices, reflecting their growing desirability among collectors.

The NB Miata, by comparison, is an underrated gem. Overshadowed by the NA’s iconic reputation, the NB is often overlooked despite its superior performance and modern features. This relative lack of demand keeps prices lower, with clean examples available for $4,000 to $7,000. For buyers seeking value for money, the NB represents a cost-effective entry into the Miata world without sacrificing the core elements of what makes these cars so beloved.

Verdict

For purists, the NA Miata is the ultimate choice. Its raw driving experience, timeless design, and iconic pop-up headlights embody the essence of classic sports car enthusiasm. It’s perfect for those who value nostalgia and an analog connection to the road.

For practical enthusiasts, the NB Miata offers a more refined package. With sharper handling, modern styling, and better safety features, it’s a roadster that blends Miata DNA with everyday usability. It’s an excellent choice for drivers who want engaging performance and creature comforts in equal measure.


The NA and NB Miatas both deliver what enthusiasts love most, pure, joyful driving. Whether you’re drawn to the NA’s classic charm or the NB’s modern refinements, there’s no wrong choice. Each generation captures the spirit of Mazda’s iconic roadster in its own unique way, ensuring that the Miata’s legacy lives on in the hearts of drivers everywhere.
