Miata values have quietly turned a corner. The cars were cheap for so long that clean, unmodified examples became rare, and the market is now rewarding originality and condition.
What is appreciating and why:
- Low-mileage, unmolested NAs, especially clean 1.6 cars and early 1990-1991 examples. First-year status and factory originality drive these.
- Special and limited editions: the 1991 British Racing Green, the M2 cars, and low-production color-and-trim runs across generations carry premiums.
- Mazdaspeed NB and clean NB2s: factory-turbo scarcity and the NB's value-sweet-spot reputation.
- Anniversary and launch-edition NDs: the 30th Anniversary in particular already trades above normal used prices.
The common thread is originality plus rust-free structure. A modified car, however well done, almost always sells for less than a stock equivalent, because the buyer pool for collectibility wants factory.
Practical guidance:
| Bucket | Direction |
|---|---|
| Clean stock NA (esp. 1.6, early cars) | Rising |
| Rust-belt project cars | Flat to falling |
| Tastefully modified drivers | Priced as drivers, not collectibles |
| Special editions, all gens | Premium |
Two cautions that protect value:
- Keep it original if collectibility matters. Save the factory parts; reversible mods preserve value, cut ones destroy it.
- Structure is the whole game. A rare trim with rotten frame rails is a parts car with a nice badge. The number-one structural killer erases collector value fast.
Decisive take: if you want an appreciating Miata, buy the cleanest, most original, rust-free example of a desirable spec you can find and leave it alone. Condition and provenance carry the value, not mileage on the odometer or a folder of receipts for mods.
