Convertible vs. Hardtop Miata: Which should YOU buy?

Ever since Mazda introduced the MX-5 Miata in 1989, this pint-sized roadster has captured the hearts of driving enthusiasts worldwide. Praised for its simple, lightweight design and drop-top fun, the Miata remains a standard-bearer for affordable sports cars. Yet among Miata lovers, the debate rages on: should you go soft top or hardtop?

Soft top Miatas emphasize the old-school roadster charm and the quickest “drop the roof and go” experience. Hardtop Miatas, on the other hand, whether it’s a removable top for older generations or a power retractable version on newer models, bring added stiffness, better security, and a more coupe-like silhouette. This guide explores both sides of the coin across all Miata generations, from the classic NA with pop-up headlights to the modern ND with its sleek Retractable Fastback (RF) option. If you’re on the fence, read on to find out which roof style suits your lifestyle best.

Quick Generational Overview

Miata history can be broken down into four main generations. The NA (1989–1997) is the original icon with pop-up headlights and a featherlight chassis. You can have it with a manual soft top by default or an optional removable hardtop. The NB (1999–2005) inherits much of the NA’s charm but swaps pop-up lights for fixed ones, features a 1.8L engine exclusively, and also offers an optional removable hardtop.

Moving into modern territory, the NC (2006–2015) gains a 2.0L engine and a bit more weight but still delivers stellar handling. It also introduces the factory Power Retractable Hardtop (PRHT) for those craving a folding metal roof. Finally, the ND (2016–present) marks a return to ultralight form with a 2.0L SkyActiv engine, weighing in at under 2,400 lbs. It comes with either a manual soft top or an RF version, featuring a power-operated targa-style roof for a unique fastback look.

The Classic Debate: Soft Top vs. Hardtop in Older NA/NB Miatas

Removable Hardtops (NA/NB)

NA and NB generations rely on a fiberglass or composite removable hardtop for those who want extra durability and security. Because older soft tops may not hold up as well to harsh winters, the hardtop offers better insulation against cold, wind, and rain. People living in colder climates often love the added weather protection and reduced chance of leaks. Plus, with a solid roof instead of cloth, thieves are less likely to break in, or slash through, if the car is parked outside overnight.

A bonus for driving enthusiasts is the improved chassis rigidity. The NA/NB platform can feel a bit more solid with a removable hardtop in place, resulting in sharper handling and fewer squeaks or rattles. A lot of owners switch to the hardtop during cold months, then pop it off in spring for that pure convertible vibe. Others leave it on year-round because they like the look and convenience.

Soft Top Pros & Cons in NA/NB

For many purists, the NA and NB are all about that “roadster” feeling, a quick flip of the latches, drop the top in seconds, and enjoy the sun and wind. With the top down, you have a fully open cabin, free of any bulky buttresses or roll hoop structures blocking your view. Another plus is weight reduction: a soft top alone keeps the Miata at its lightest, preserving that famously nimble cornering character.

On the downside, original vinyl tops with plastic rear windows can wear out over time, leading to leaks or foggy, cracked plastic. Fortunately, you can upgrade to a higher-quality Robbins or OEM top with a glass window and better insulation. If cost is a concern, most NA/NB Miatas come with only the soft top, meaning you’d have to spend extra, often $1,000 to $2,000 or more, for a removable hardtop. Overall, choosing between a soft top or adding a hardtop usually depends on climate, budget, and whether you prioritize quick drop-top fun or year-round comfort.

Which to Choose for NA/NB?

If you live in a mild climate and mostly drive your Miata on sunny days, sticking with the soft top alone makes sense. It’s cheaper, lighter, and embodies the classic Miata spirit. If you plan to drive in all kinds of weather or park in not-so-secure locations, a removable hardtop adds real benefits: extra stiffness, better security, and greater comfort in colder seasons. Many owners do both, keeping the soft top in place and buying a hardtop for the winter or whenever they want a coupe-like experience.

The NC Generation: Soft Top vs. Power Retractable Hardtop (PRHT)

The NC introduced a new dimension to the Miata formula by offering two distinct roof types from the factory. You can still get the traditional manual soft top or go with a powered folding metal roof known as the PRHT.

NC Soft Top

The manual soft top on the NC is similar in spirit to the NA/NB, though it’s physically larger because the entire car is bigger. It’s still straightforward to operate, unlock the latches and fold it back behind your head, but expect a bit more effort than earlier generations. Being the simpler, lighter option also means it’s often priced lower on the used market. For drivers who prioritize the most authentic “drop-top” experience and minimal weight, the soft top NC fits the bill perfectly.

NC PRHT

Mazda’s Power Retractable Hardtop transforms the NC into a neat little coupe in just 12 to 15 seconds with a push of a button. This version is ideal if you commute daily or experience colder winters, thanks to its improved insulation and reduced road noise. It’s generally 70–80 pounds heavier than the soft top, so the handling difference might matter if you spend time on track. Otherwise, it’s hardly noticeable in typical street driving. The PRHT also increases security, since breaking through a metal roof is much harder than slashing fabric.

Verdict for NC: If you love simplicity, slightly sharper handling, and a lower purchase price, go with the soft top. If you’re after a quieter cockpit, better all-weather performance, and a more coupe-like vibe, the PRHT justifies its modest weight penalty.

The ND Generation: Soft Top vs. RF (Retractable Fastback)

The current ND generation pushes the Miata concept forward with a lighter, more efficient design while still offering two roof choices: the classic soft top or the striking Retractable Fastback (RF).

Performance Differences

Both the ND soft top and RF are powered by the same 2.0L SkyActiv engine. From 2016 to 2018, that meant around 155 horsepower, while 2019 and onward (the “ND2”) got a bump to about 181 horsepower. Because the RF’s retractable mechanism adds 50–110 extra pounds, it can be a tad slower in a sprint, but in everyday driving, the difference is small. Some owners find the RF’s added weight over the rear helps it feel more planted, while the lighter soft top might feel slightly livelier through corners.

Comfort & Cabin Experience

Those seeking the most open-air sensation might prefer the ND soft top. It’s quick and easy to raise or lower in a few seconds, often without leaving the driver’s seat. Meanwhile, the RF’s roof operation takes about 13 seconds and has to be done at very low speed (about 6 mph or less). With the RF, you also get more of a targa feel when the roof is retracted, meaning the rear buttresses stay put, leading to a different driving sensation and sometimes tricky rear visibility.

Noise and insulation also differ. The soft top, while improved over older Miatas, can let in more wind noise at highway speeds. The RF is more coupe-like, so it’s quieter when the roof is up. One practical consideration is headroom: the soft top typically offers about half an inch more clearance, which can matter a lot if you’re tall.

Styling & Image

Style often plays a big role in deciding between the ND soft top and the RF. The soft top looks timeless, echoing classic British roadsters with a modern twist. The RF, on the other hand, boasts a futuristic fastback design that stands out, even among other convertibles. People sometimes don’t realize it’s a convertible until they see the roof fold away.

Cost

The ND soft top starts out at a lower base price compared to the RF. In many markets, the difference is a few thousand dollars. The RF, however, tends to hold its value well, partly because it’s unique and appeals to drivers who want that coupe-plus-convertible functionality.

ND Verdict: Pick the soft top if you want that minimal-weight, “drop the roof in three seconds” experience or if you’re mindful of budget and prefer maximum headroom. Pick the RF if you love the style, want a quieter ride, and don’t mind paying a bit extra or carrying a bit more weight.

Usage Scenarios

Weekend Toy vs. Daily Driver

If your Miata is mainly for weekend fun in the sun, it’s hard to beat the simplicity and pure joy of a soft top. But if you plan to drive all year or endure snowy, rainy commutes, a hardtop or retractable roof can offer better weather protection, security, and noise control.

Track Enthusiasts

Many track events require a certain amount of rollover protection, which may be easier to handle with a removable hardtop (NA/NB) or a more rigid roof. That said, a soft top is lighter and simpler, and you can always add a roll bar under it. Just make sure the bar fits with your chosen roof.

Aesthetic Preferences

Style can be everything for some Miata owners. An NA with color-matched removable hardtop gives that retro 90s vibe, while the ND RF’s fastback silhouette is eye-catching in a thoroughly modern way. Neither is “better”, it just comes down to what makes you smile.

Cost, Maintenance & Resale

Hardtop Cost (NA/NB)

An OEM hardtop for an NA or NB can easily cost $1,000 to $2,000 or more on the used market. Color-matching can be tricky, so expect to pay more if you’re picky about an exact paint code. Some owners remove their soft top altogether and run only the hardtop, especially if they prefer the coupe style or track their car frequently.

Soft Top Replacement

Soft tops do wear out over time. A quality replacement (like Robbins or OEM) runs in the $500–$1,000 range, plus labor if you’re not doing it yourself. If your older NA has a plastic rear window, upgrading to a glass window with defroster capability is a worthwhile improvement.

Resale Value

Miatas with a clean hardtop or the newer retractable roofs often see a bump in resale. Hardtops in particular can be a major selling point for NA/NB owners. NC PRHT and ND RF models also hold their value well, since many buyers appreciate the coupe-like refinement they bring.

No matter which Miata roof style you choose, you’re in for one of the most enjoyable driving experiences on the market. With its nimble chassis, reliable powertrain, and huge owner community, the Miata remains a top pick for anyone wanting a fun, easy-to-own sports car.

If spontaneous, top-down thrills and the lightest possible setup matter most to you, a soft top is a no-brainer. If you want better noise insulation, year-round comfort, or just love that sleek coupe-like appearance, a hardtop, be it removable, PRHT, or RF, could be your best friend.

At the end of the day, you really can’t go wrong. Each Miata generation and roof style has its own strengths, and the “right” choice is the one that fits your needs, budget, and personal taste. Top up or top down, the Miata remains an all-time classic for a reason, so get out there and enjoy the drive!
