Mazda ROADSTER RF S (NDERE) – Specifications & Buyer's Guide

Introduction

The Mazda ROADSTER RF S (model code NDERE) represents the hard-top retractable variant of Mazda’s celebrated lightweight roadster aimed at drivers who want open-top driving with a more coupe-like profile. This guide gathers verified factory specifications and practical buying advice for international buyers considering a Japanese-market ROADSTER RF S (NDERE) from auction or used-vehicle listings in Japan.

Mazda ROADSTER RF S (NDERE) Overview

The ROADSTER RF S (NDERE) is a Japan-market variant of Mazda’s Roadster RF (known internationally as the MX-5 RF). The RF model retains the Roadster’s two-seater layout and sports-car intent while offering a power-retractable fastback roof for improved weather protection and a different silhouette. The NDERE model code corresponds to the RF variant and the "S" trim level shown in available factory data. This article uses verified factory specification fields provided for the NDERE code; where details are not available they are clearly noted.

Mazda ROADSTER RF S (NDERE) Specifications

Engine and Performance

Verified factory data for the NDERE shows a 1,997 cc engine paired with a 6-speed manual transmission and rear-wheel drive layout. These facts indicate a focus on a driver’s experience: a relatively light kerb weight of 1,110 kg combined with a manual gearbox and FR drive typically yields an engaging, balanced driving character in similarly configured roadsters.

Because specific horsepower (PS/hp), torque (Nm), and official fuel economy figures were not supplied in the verified input, this article does not list those values. When you inspect a specific vehicle listing, confirm the engine output and torque figures shown on the registration or inspection sheets. These values can vary by market, tuning, or special editions.

Exterior Design and Dimensions

The supplied dimensions—3,915 mm long, 1,735 mm wide and 1,245 mm tall—confirm a compact, low-slung sports-car footprint that favours agility and parking friendliness in tight urban environments. The RF nameplate denotes the retractable fastback roof design used by Mazda for a coupe-like appearance with the flexibility of an open-top drive; the NDERE code corresponds to an RF variant in factory records.

Practical exterior highlights for buyers to verify on individual cars include the condition of the retractable roof mechanism (operation, seal condition), body panel alignment, and corrosion or stone-chip damage around lower body panels and front apron. The light kerb weight listed (1,110 kg) supports nimble handling but also makes condition of suspension components and bushings important during inspection.

Interior, Comfort and Technology

The NDERE factory data confirms the S-grade trim designation but does not list interior equipment in detail. Typical features for the ROADSTER RF S in many markets include a driver-focused cockpit, two-seat layout, and a retractable roof mechanism that stores in a way to preserve trunk space better than some convertible designs. For each specific vehicle, check for confirmed items such as infotainment system version, air conditioning, seat materials, and any optional packages fitted at the factory or by previous owners.

Verify the condition of:

• Seats and seat rails (for wear and binding)
• Roof operation and interior seals
• Instrument cluster and electronics for error codes or warning lights

Fuel Economy and Everyday Practicality

Official Japanese fuel economy figures (JC08 or WLTC) were not included in the verified data for NDERE and therefore are not listed here. The ROADSTER RF’s compact size and 2.0L engine in similar models generally make it suitable for daily driving, especially for single drivers or couples who prioritize driving enjoyment. However, limited cargo capacity and two-seat layout reduce practicality for families or frequent long-haul luggage needs.

If fuel economy is a major purchase factor, request the exact WLTC or JC08 figures from the seller or check original Japanese brochures and certification sheets attached to the car.

Is the Mazda ROADSTER RF S (NDERE) a Good Used Car to Buy?

Strengths:

• Driver-focused layout: manual gearbox and FR configuration appeal to enthusiasts.
• Compact dimensions and light weight favour handling and urban usability.
• RF roof gives coupe-like protection with open-top flexibility.

Limitations:

• Two-seat layout limits passenger and cargo versatility.
• Verify roof mechanism condition — repairs to retractable hardtops can be costly.
• Some specification gaps (power output, fuel economy) must be confirmed per car.

Inspection considerations:

• Confirm VIN/chassis and matched model code NDERE on documents.
• Inspect roof operation, seals, and hydraulic/electrical components.
• Check for service history, rust in underbody areas, and timing-belt/chain service intervals if applicable.
• Obtain a vehicle history check (see AutoCheck.jp below) and, if possible, an independent mechanical inspection.
