If you're thinking NB (last generation) MX-5, I think you're on the right track. If you do go MX-5, first decide whether you want an NB1 or NB2/NB-FL. The NB1 was made from 1998-2000. (Model year 1999 and 2000 in the US, but 1998-2000 elsewhere.) It has a more oval grille, nicer looking (IMO) but less effective headlights, smaller brakes except on the Sport (they say "Hard S" on the doorjamb) models, and generally 15" wheels in a pleasing convex 5-spoke that reminds me of 1990s Porsche wheels. In the US there was only a 1.8, but I think you guys had a 1.6, too. The US 1.8 runs on regular gas. Of NB1's, I think only the 10th Anniversary global special edition (blue with blue top and blue ultrasuede seat inserts) and maybe the 2000 special/limited editions (different for every country) had 6-speeds, but the difference between the 6MT and the 5MT is minimal. The NB2/NB-FL (Face Lift) was made from model year 2001 until the NC. It has uglier (IMO) but more effective projector headlamps, a rounded trapezoid grille, taillights more like the original Miata's. Under the skin, the NB-FL is marginally stiffer, but also heavier. The engine is also improved in some respects. It has VVT, and while it makes no more peak horsepower there's more torque under the curve than on the old engine, and you can feel it at once. However, it also requires midgrade fuel, and I think NB-FL's get inferior fuel economy than NB1's. The stock wheels for the NB-FL are also lesser, being ugly flat swept 5-spokes. Base models have 15", but any upgraded model will have 16" wheels. In the US, the incredible big brake package was standard through the range from 2003, along with 16" wheels. One key feature to look for is ABS. In America, at least, it is very rare on Miatas. Open the hood, and make sure you see a black box on the left side next to the firewall. If you see a large windscreen wiper fluid bottle, the car does not have ABS. (Yes, I drive a Miata. An NB-FL, though I do not believe that biases the comparison above.) One other consideration, though: did GM ever import the Opel Speedster into Australia? That car is basically a Lotus Elise with a sexier (IMO) body and a lesser engine. It's a better drive than even the MX-5, and only marginally lower utility. If GM residuals in Australia are similar to GM residuals in America, you may be able to pick one up very cheaply.
