If you want a new affordable roadster in the U.S., the 2026 Mazda MX-5 Miata is the clearly documented choice in the research available for this guide. Used FIAT 124 Spider, BMW Z4, Porsche Boxster, and Mercedes-Benz SLK-Class models are worth considering, but their affordability depends on the specific car, its condition, and local listings. The Toyota GR86 and Subaru BRZ are useful sports-car cross-shops, but they are coupes, not roadsters.
What counts as affordable?
For a new car, this guide uses the documented 2026 MX-5 Miata Sport soft-top starting MSRP as a reference point, not a universal affordability cutoff. For used cars, there is no single price threshold here: asking prices change with location, model year, mileage, title history, and condition. The available research does not support a current, comparable national price ranking for ten roadsters.
Do not treat MSRP, a used-car asking price, and a transaction price as interchangeable. Before you shop, set a total budget that includes the vehicle, taxes and registration, insurance, and any repairs the specific car may need.
Current new-roadster option: 2026 Mazda MX-5 Miata
Mazda’s 2026 U.S. model information describes the MX-5 Miata as a two-passenger, rear-wheel-drive car with a 2.0-liter engine producing 181 horsepower and 151 lb-ft of torque. A six-speed manual is standard; an automatic is available on Grand Touring trims. Buyers can choose a manually operated soft top or an RF with an electronically retractable hardtop. Mazda’s vehicle page and its 2026 pricing release are the sources for these model details.

There is a price discrepancy between Mazda’s published materials. Mazda North American Operations’ January 2026 pricing release lists $30,430 MSRP for a Sport soft-top with a six-speed manual. Mazda’s current vehicle page displays a Sport starting price of $30,730 and lists destination and handling at $1,315, or $1,360 in Alaska. These figures are not a final out-the-door price: options, taxes, title, license, and dealer pricing may add to the amount. Confirm the current price and fees with a written dealer quote.

Used roadsters to investigate
Used-car roundups identify the FIAT 124 Spider, BMW Z4, Porsche Boxster, and Mercedes-Benz SLK-Class as candidates for budget-conscious sports-car shoppers. That makes them worth investigating, not guaranteed bargains or a verified top-four ranking. A broad used-car roundup does not establish what a particular example will cost to buy or maintain.
Road & Track’s used-convertible guide also covers the Boxster and notes that the Honda S2000 is no longer in its cheap category. Treat that as a caution against assuming the S2000 still fits a low budget, not as a national price estimate. Read Road & Track’s used-convertible guide.

This automotive diagnostic scanner is designed for wide vehicle coverage; please check compatibility with your vehicle before purchase
For any used model, compare actual local listings for the same year and similar mileage, title status, and condition. A model name alone cannot establish reliability or likely repair expense.
How to compare your shortlist
- Decide whether a roadster body is essential. If you want an open top, keep the Miata and used convertible candidates in the comparison. Consider the GR86 and BRZ only if a coupe also meets your needs.
- Compare the full purchase price. Label each number as MSRP, asking price, or dealer quote, and note its source and date. For used cars, compare local examples with similar year, mileage, title status, and condition.
- Check configuration and practicality. Confirm the roof type, seating, and transmission for the specific trim or used listing. The Miata, for example, has two seats and offers soft-top and RF roof choices.
- Assess the individual used car. Review its VIN and history, examine its condition, and arrange an independent pre-purchase inspection. The research here does not establish a model-wide reliability promise or a repair-cost forecast.
- Get a written quote for a new Miata. Ask the dealer to itemize the vehicle price, destination, options, taxes, title, license, and any dealer charges. Mazda’s published starting figures differ, so verify the current amount.
Which one should you choose?
If you want a new, clearly documented two-seat roadster, start with the 2026 MX-5 Miata and choose between its manual or available automatic configuration and soft-top or RF roof. If you are shopping used, investigate the 124 Spider, Z4, Boxster, and SLK-Class by comparing specific local cars rather than relying on a generic ranking. If a fixed roof or extra seats are acceptable, add the GR86 and BRZ as coupe alternatives.

Do not assume it is. Road & Track’s used-convertible guide notes that the S2000 is no longer in its cheap category. Check current local listings to see whether one fits your budget.
