MX-5 MiataConvertible
2.0L I4 · Convertible
The 2020 Mazda MX-5 Miata is the fourth generation (ND) of the world's best-selling two-seat roadster, now in its fifth year of production. Mazda kept the formula simple: a lightweight 2,341-lb chassis, rear-wheel drive, and a 181-hp 2.0L four-cylinder that rewards a driver who actually enjoys shifting gears. It's not fast in a straight line, but few cars at any price point feel this alive in corners. For 2020, the MX-5 benefits from a mid-cycle bump that brought the 2.0L up from 155 hp (2016–2018) to 181 hp. The soft-top Miata starts under $27k, making it one of the last affordable pure sports cars on the market. The RF (retractable fastback) hardtop variant commands a premium but shares most mechanicals. This is not a practical daily driver in Wisconsin. It sits low, seats two, has a tiny trunk, and most owners store it October through April. But as a weekend car or warm-season commuter, it's nearly impossible to beat for the money.

Watch for
- Extremely limited cargo space — trunk holds about one carry-on bag
- Not a practical year-round Wisconsin daily driver; low ground clearance and no winter tires available in stock size easily
- Soft top requires care to avoid leaks and tears over time

Maintenance schedule
- 1 Every 7,500 miles or 6 months — whichever comes first Engine Oil & Filter Change
Mazda specifies 0W-20 full synthetic, 4.5 qts with filter. Given Wisconsin winters, don't stretch intervals — cold starts in sub-zero temps are hard on oil. If you track the car, drop to 5,000-mile intervals.
- 2 Every 7,500 miles Tire Rotation
RWD cars wear rear tires faster under spirited driving. Keeping rotation on schedule extends tire life significantly and helps you catch uneven wear from alignment issues early.
- 3 Every 2 years or 30,000 miles Clutch Fluid Inspection (Brake/Clutch Hydraulic System)
This car uses DOT 3 fluid shared between the brake and clutch hydraulics. Degraded fluid accelerates master cylinder wear — the known weak point on these cars. Flush on schedule.
- 4 Every 30,000–45,000 miles (more often if tracked) Rear Differential Fluid Change
The rear diff on 2016–2020 MX-5s has a history of noise issues. Fresh 75W-90 GL-5 fluid keeps bearing surfaces lubricated and can help delay or prevent early wear. Don't skip this one.
- 5 Every spring and fall Soft Top Inspection & Conditioning
Before winter storage, clean and condition the fabric top and lubricate the latches. Inspect weatherstripping for cracks. A neglected top can leak onto interior electronics and carpets.
- 6 Every 30,000 miles or 30 months Air Filter Replacement
Part B6Y1-13-Z40. The Skyactiv engine is sensitive to airflow; a clogged filter hurts both power and fuel economy noticeably on a car this light.
- 7 Every 120,000 miles Spark Plug Replacement
Mazda uses iridium plugs with a long service life. If you're seeing misfires (P0300) before 120k, check plugs first — they're the cheapest misfire fix.
- 8 Every 20,000 miles Cabin Air Filter Replacement
Part G6Y4-61-J10. Easy DIY swap. Wisconsin spring means pollen; a blocked cabin filter kills what little A/C capacity this small car has.
Always defer to the manufacturer's service manual for warranty-mandated intervals.
Cost of ownership
Annual maintenance
$400 – $800
Fuel
At 30 mpg combined and ~10,000 miles/year (seasonal use), expect roughly $900–$1,100/year at $3.00–$3.50/gal. Most Wisconsin owners drive this car only April–October, so real-world annual fuel costs are lower.
Insurance
Typically moderate — sports car surcharge applies, but the low horsepower and low MSRP keep premiums reasonable. Expect $900–$1,400/year for full coverage on a clean driving record in the Lake Geneva area.
The MX-5 is one of the cheaper sports cars to own. Parts are available, labor time is low on most jobs (small, simple engine bay), and the drivetrain rarely needs major intervention under 100k miles with normal care. The main budget surprises are clutch hydraulics (~$250–$400 when it goes) and rear differential work ($800–$2,000 if noise develops). Annual maintenance for a seasonally driven car should land well under $800 in most years. Factor in winter storage costs if applicable.
Seasonal care
Lake Geneva, WI Winter
- This car is not built for Wisconsin winters — store it before first snow. Low ground clearance (5.1 in) and summer performance tires are not safe on ice or in snow.
- Before storage: change oil so acidic used oil doesn't sit in the engine all winter. Fill the gas tank and add a fuel stabilizer to prevent varnish buildup.
- Disconnect or use a trickle charger (maintainer) on the battery during storage. The small battery in the MX-5 will self-discharge and sulfate over a 4–6 month storage period.
- Clean and condition the soft top before storing. Store in a garage if possible — UV and freeze-thaw cycles crack weatherstripping fast.
- If the car must be driven in winter, switch to a dedicated winter tire set (requires sourcing correct 195/50R16 or 205/45R17 in winter compounds). Never drive on summer performance tires below 40°F.
- Check brake fluid condition before storage — DOT 3 absorbs moisture and freezing temps accelerate internal corrosion in the clutch master cylinder.
Summer
- Check tire pressure every 2–3 weeks in summer — for every 10°F rise in ambient temp, pressure increases ~1 PSI. The MX-5's narrow tires are sensitive to over-inflation on hot pavement.
- Inspect the soft top for UV cracking and ensure latches are fully seated before highway driving. Wind load at 70+ mph stresses a poorly latched top.
- The A/C system is adequate but not powerful — if cooling is weak, check refrigerant charge first. Cabin filter replacement helps airflow noticeably.
- After winter storage, flush brake/clutch fluid before driving aggressively. Moisture-laden fluid boils at lower temperatures, a real concern on track days or mountain roads.
- Wash the undercarriage thoroughly in spring to remove road salt residue from the previous season. The MX-5's floor pans and frame rails can trap salt in seams.
Comparable vehicles
2020 Toyota
86
Also RWD, 2-seat-focused, naturally aspirated — slightly more power (205 hp), a fixed roof, and a firmer ride. Less steering feel than the Miata but more cabin space and a usable back seat.
2020 Subaru
BRZ
Mechanically identical to the Toyota 86, built on the same platform. RWD coupe with similar price point. Better AWD availability if you cross-shop the WRX instead, but the BRZ is the direct Miata coupe competitor.
2020 Fiat
124 Spider
Built on the same ND Miata platform but with a turbocharged 1.4L engine and Italian styling. Slightly more torque, softer tuning, different character. Rarer, with harder parts sourcing — factor that in for a Wisconsin buyer.
2020 Mini
Cooper Convertible
FWD convertible in a similar price range. More practical with a back seat and bigger trunk. Lacks the Miata's driver engagement and RWD dynamics, but a better year-round option for Wisconsin if top-down is the priority.
