Used Mazda Miata NA Buying Guide: Rust, Crank, Title

A used first-generation Mazda Miata, the NA roadster sold in the U.S. from the 1990 to 1997 model years, is worth buying when the sills are solid, the crank pulley is quiet and the title is clean. On Nov. 5, 2026, the NHTSA recall API for 1990 returned 92V159000 for an accessory hardtop hoist whose buckles can break, plus an aftermarket lamp campaign. The MX-5 MIATA string returned no rows for 1990, 1993 or 1997, so do not read that as a clean bill. Run the VIN on the NHTSA recall lookup before you pay.

Which Miata this is

Wikipedia lists the NA as the first MX-5, with a 1.6-liter engine early and a 1.8-liter from 1994. Match the engine and trim to the VIN. Our Miata buying guide covers later generations, and our Mazda recall check shows the VIN search.

Sills, top and drains

Rust starts at the rear sills and the rocker panels, often from blocked soft-top drains behind the seats. Press on the sills, check the floor and look under carpets. Check the soft top for tears and the rear window for clouding, and ask if a hardtop comes with it.

Crank pulley and short-nose cars

Some early 1.6 cars are known for a crank pulley wobble that can damage the crank nose. Watch the pulley at idle for wobble and listen for a knock. Ask for receipts for the timing belt and water pump, and check for a leaking oil cooler or cam seals.

A test drive that tells you something

Drive it from cold, not after the seller has warmed it up. Listen for ticks and knocks at start-up, watch the mirror for smoke, and check that every gauge and warning lamp comes on and then goes out. Try every gear, a hard stop and a slow full-lock turn both ways, then look underneath for fresh drips. Bring a flashlight and a magnet for filler checks on the lower doors and rear wheel arches.

Insurance, registration and inspection

Call your insurer with the VIN before you pay, because an older sports car or truck can be valued low after a loss. Ask your state DMV whether the vehicle needs a VIN inspection, a safety inspection or an emissions test at transfer, and what happens if a prior registration lapsed. Budget for new tires if the date codes are old, even when the tread looks fine.

When to walk away

• Soft or holed sills and rocker panels.
• A wobbling crank pulley.
• A timing belt with no receipt or date.
• A VIN that does not match the title.

Questions to ask the seller

• Has the crank pulley been checked or replaced? Was the work done, and is there a receipt?
• When was the timing belt done?
• Has the car had sill or floor repairs?
• Has the title ever been branded?

Reading the history on an older car

Do not expect a complete service log. Many independent shops never reported their work, so the report matters most for title brands, odometer readings at title transfers and registration gaps by state. A car that moved from a coastal or rust-belt state to a dry one may have been retitled; look at the dates and ask why. An approved NMVTIS check adds salvage and junk records from insurers and recyclers. If the odometer readings go backward or the car shows as exempt, ask for the paper trail before you price it. Our odometer discrepancy guide explains what those entries mean.

Private-sale paperwork

Most cars like this sell privately. Make sure the name on the title matches the seller ID, the VIN on the title matches the plate and the stamping on the car, and any old lien is released in writing. Our lien release guide walks through that step. Pay by a traceable method, get a dated bill of sale, and do not accept an open title signed by someone who is not present.

How to price it

NA Miatas sell as cheap, fun roadsters with a wide price spread. Compare recent private sales and dealer listings for the same year, engine and transmission, then subtract rust, top and timing repairs.

What the report costs

As of early November 2026 a CARFAX bought direct usually costs around $44.99, and AutoCheck sits a little lower. We are a licensed CARFAX and AutoCheck reseller, not affiliated with CARFAX, AutoCheck or Experian. Our guest price has been about $5.50 a report, about $4.50 for members, and about $6.75 for a CARFAX and AutoCheck bundle. Confirm the price at checkout, since it can change.

On a car this old, read the report for title brands and odometer readings first; service entries are often thin.
