Older Used Mazda Miata Overview (1998 - 2015), Reliability, Possible Maintenance Problems, Overall Pros And Cons

In today's very high-priced used car market, it may be the right time to look at "older" models that have aged well as a way to save significant dollars.

And the Mazda Miata is certainly one of those models due to its superior reputation for reliability and longevity. This is vital when buying an older vehicle as ongoing repair costs could offset the initial upfront savings.

This doesn't mean an older Miata is a sure thing repair-wise. All vehicles have issues.

In addition to its solid build quality, a lot of it will come down to a specific vehicle's proper maintenance history as well as the environmental conditions and driving habits of the previous owner(s) ... and with a little luck thrown in.

What it does mean is that older Miatas do indeed have some good DNA to start with. In fact, history has shown that a well-maintained Miata lasts in the 200,000 mile range, with some documented going much further ... with the key being "well-maintained".

And by "older", I'm generally referring to Miatas that are 10+ years old, which would mean those from its second and third generations, those produced for the 1998 - 2015 model years.

I've driven a number of these and they've all been a blast to drive. Credit goes to the ultra-responsive steering, the communicative handling, an energetic engine, the short throw manual shift, and a rear-wheel drive with excellent weight distribution.

And I'm far from alone in this opinion. These older models were consistent winners of Cars.com's "Best Bet Award", not to mention Edmunds.com's "Used Car Best Bet Award", along with their "Consumers Most Wanted" and "Editors Most Wanted" Awards.

J.D. Power chimed in with a 4.5 (out of 5) for Performance and a perfect 5 for its Automotive Environmental Index for many of these as well.

2nd and 3rd Generation Mazda Miata Reliability

The second-generation (NB, 1999-2005) and third-generation (NC, 2006-2015) Mazda Miata have earned an excellent reputation for long-term reliability. Unlike many affordable sports cars, both generations feature relatively simple, naturally aspirated engines, durable manual transmissions, and low overall maintenance costs. While age-related repairs become more common as these cars accumulate miles, the Miata remains one of the most dependable roadsters ever built.

The NB is widely regarded as one of the most reliable sports cars of its era thanks to its straightforward mechanical design and proven drivetrain. The newer NC introduced more modern technology and a larger chassis but retained Mazda's reputation for durability. Properly maintained examples of either generation commonly exceed 200,000 miles without requiring major engine or transmission repairs.

Common Reliability Issues

• Rust (primarily NB models): The biggest concern isn't the drivetrain—it's corrosion. Rust around rocker panels, rear wheel arches, frame rails, and suspension mounting points can be severe on vehicles from northern climates.
• Soft top wear: Convertible tops eventually develop tears, cloudy rear windows (early NB models), or leaking seals after years of exposure to the elements.
• Cooling system maintenance: Radiators, hoses, and thermostats become common maintenance items as the cars age. Plastic radiator end tanks can eventually crack, particularly on higher-mileage NB models.
• Suspension wear: Shock absorbers, bushings, sway bar links, and ball joints gradually wear out, especially on cars driven enthusiastically.
• Clutch replacement: Manual transmission clutches typically last well over 100,000 miles but eventually require replacement like any performance-oriented vehicle.
• Wheel bearings: Some higher-mileage cars develop wheel bearing noise, particularly if they have seen track use or aggressive driving.
• Minor oil leaks: Valve cover gaskets and front crankshaft seals may begin leaking as mileage climbs but are generally inexpensive repairs.

NB (1999-2005) Reliability Highlights

• Extremely durable 1.8-liter four-cylinder engine.
• Simple electronics reduce the likelihood of expensive electrical problems.
• Five-speed manual transmission is exceptionally reliable.
• Six-speed manual models are also durable but slightly more expensive to repair if problems develop.
• Rust is often a bigger buying concern than mechanical condition.

NC (2006-2015) Reliability Highlights

• Durable 2.0-liter MZR engine with few widespread mechanical problems.
• Improved crash safety and overall refinement without sacrificing reliability.
• Automatic and manual transmissions generally have excellent longevity.
• Power Retractable Hard Top (PRHT) models have proven surprisingly reliable, although occasional motor or latch repairs can occur with age.
• Suspension and cooling system maintenance become the most common repairs after 100,000 miles.

Before Buying a Used Mazda Miata

• If you may be trading in another vehicle, it's important to find out what it's worth before negotiating with a dealer. While no trade-in quote service is a perfect predictor, this one seems to be fairly accurate: free trade-in estimate.
• Getting multiple dealers to compete for your business online, before actually going to a dealership, usually results in more negotiating leverage and often leads to a better deal. You can browse current listings here and select several vehicles to create this competition.
• Or, if you may be in the market for a "new" Miata, this has been my most effective negotiation method for new cars.

Long-Term Ownership

• 0–100,000 miles: Typically requires only routine maintenance.
• 100,000–150,000 miles: Suspension components, cooling system parts, and clutch replacement become more common.
• 150,000–250,000+ miles: Well-maintained examples often continue running reliably with normal age-related repairs rather than major drivetrain failures.

Reliability Verdict

• Overall reliability: ★★★★★ (Excellent)
• Engine reliability: Excellent.
• Transmission reliability: Excellent.
• Maintenance costs: Low for a sports car.
• Biggest concern: Rust on NB models and deferred maintenance rather than major mechanical defects.

Bottom line: Both the second- and third-generation Mazda Miata are among the most reliable sports cars available on the used market. Their simple engineering, dependable powertrains, and relatively inexpensive maintenance make them excellent choices for enthusiasts seeking an affordable, long-lasting roadster. When shopping, focus more on rust, maintenance history, and overall condition than on mileage alone.

Performance: While the Miata offers a balanced driving experience, some enthusiasts may find its performance lacking compared to more powerful sports cars.

Road Noise: Due to its convertible nature and lightweight construction, the Miata can be prone to significant road noise, especially at higher speeds or on rough roads.

Rear-wheel Drive: While rear-wheel drive enhances the Miata's handling characteristics, it can pose challenges in inclement weather conditions.

Third Generation Mazda Miata (2006 - 2015) Overview

This version comes with a 170 horsepower 2.0-liter incline four-cylinder engine, which is nearly as much power as the turbo charged MazdaSpeed models produced in 2004 and 2005. This engine is mated with either a 5-speed or 6-speed manual transmission, or a 6-speed automatic.

This Miata is offered in four trim levels: SV, Sport, Touring and Grand Touring.

With slight variations in the model years, the SV and Sport were initially fairly sparse when it comes to features, both mostly aimed at weekend racing enthusiasts. The SV basically ccame with power windows and anti-lock brakes but not A/C, while the Sport added 17-inch alloy wheels, P205/45R17 high performance tires, and a leather-wrapped gearshift knob.

But by 2010, the SV had been dropped and the then base Sport came fairly decently-equipped with power windows, power mirrors, air conditioning, 16-inch alloy wheels, a black vinyl convertible top with a rear glass window, a 6-speaker audio system with a CD/MP3 player and an auxiliary input jack, cloth seats, and a leather-wrapped steering wheel.

It's really the well-equipped Touring model that usually attracts more interest, while the Grand Touring is fairly luxurious. And in a major advancement for everyday drivers, a power-operated hardtop was introduced in 2007 for additional safety and enhanced quietness.

In 2008, a Special Edition model in Icy Blue paint was offered, while in 2009 the Miata got a mild refresh which included some engine revisions that slightly boosted both power and fuel economy.

Also added was a more aggressive grille, a new headlight and taillight design, a stiffened suspension, and several new convenience features (an auxiliary input jack and two additional speakers for the base audio system, an auto-dimming mirror for the Touring model, and automatic climate control for the Grand Touring).

Second Generation Mazda Miata (1998 - 2005) Overview

While these are getting harder to find out there, they certainly exist in good condition. I just did a search (on March 5, 2024) and found 5 with less than 60,000 miles within 200 miles of my location. One had just 36,000 miles.

And yes, I'm willing to travel a good distance for the right vehicle, and actually much further. And I find that a lot of these older Miata owners are enthusiasts and have taken good care of them, and often had other cars for their daily vehicles, hence the far below-average mileage.

While this version also has the sharp steering and overall dynamic handling the Miata is famous for, it is also a bit smaller and therefore a bit more cramped.

Originally under the hood of this Miata was a 1.8-liter four-cylinder engine that delivered 140 horsepower and 119 pound-feet of torque. These Miatas can be found with either the standard 5-speed manual transmission or the optional 4-speed automatic.

And like the third generation, the base trims were lightly equipped, but models can also be found with more upscale features such as leather upholstery and a Bose sound system.

For the 2000 model year, the lineup was simplified to include the Miata and Miata LS with a choice of three option packages. In addition, 2000 saw the debut of a Miata Special Edition with a 6-speed manual transmission.

For 2001, horsepower was upped to 155 and the Special Edition's 6-speed manual was offered on the Miata LS as an option.

2004 saw the addition of variable valve timing which increased engine output, as well as the introduction of the 178 horsepower turbocharged Mazdaspeed model with its high-performance suspension and unique exterior styling elements.
