Mazda MX-5 II (NB) (1998 – 2005)

Reliability score : 8.2/10

The Mazda MX-5 Generation II (NB) was introduced in 1998 as the successor to the legendary NA. While it lost the iconic pop-up headlights due to pedestrian safety regulations and aerodynamic improvements, it gained a significantly stiffer chassis, a more aerodynamic body, and a glass rear window with a defroster. In 2001, the model received a major facelift (known as the NBFL or NB2), which introduced projector headlights, a revised interior with better seats, additional chassis bracing, larger brakes (Sport trim), and Variable Valve Timing (VVT) for the 1.8L engine. Mechanically, the NB is incredibly robust, but its reputation is heavily marred by severe rust issues, particularly on the front chassis rails—a design flaw unique to this generation. Overall, it remains one of the purest, mos

✅ Strengths

Unmatched driving dynamics, perfect 50:50 weight distribution, and communicative steering.
One of the best manual gearboxes in automotive history (both 5-speed and 6-speed).
Mechanically bulletproof engines that easily exceed 200,000 miles with basic maintenance.
Massive aftermarket support and incredibly cheap, plentiful spare parts.
Glass rear window with defroster (a huge upgrade over the NA's plastic window).

⚠️ Weaknesses

CATASTROPHIC RUST ISSUES: Front chassis rails, rear sills, and wheel arches rot from the inside out.
Cramped interior: Drivers over 6ft (1.85m) will struggle with headroom and legroom.
High noise levels at highway speeds (wind, road, and engine noise).
Very small trunk capacity and limited interior storage.
Prone to water leaks if the soft top rain rails or drain holes are clogged.

🎯 Verdict

The Mazda MX-5 NB is arguably the sweet spot of the Miata lineage: it retains the raw, analog feel of the NA while offering better chassis rigidity, improved aerodynamics, and a more livable interior. Mechanically, it is one of the most reliable sports cars ever built. However, RUST IS THE ULTIMATE KILLER. The front chassis rail rot is a fatal flaw specific to the NB generation. You must buy this car based entirely on the condition of its chassis, not its mileage or engine. If you find a rust-free example (or one that has been professionally repaired and undersealed), it is an absolute joy to own and a guaranteed future classic. If you ignore the rust, it will become a financial nightmare.
