Here in the Philippines the new Miata is rather overpriced, imo. The MX-5 costs P2.2M, while the 3.8 Gen Coupe costs 1.73M for the M/T and 1.85M for the matic. They're not in the same price range at all, so it's hard to make a comparison when the GC is so much more bang for buck.
As for competitors, well, I was going to get a 3.8 GC, but wound up getting the new Subaru Legacy GT. Slightly pricier, but the combination of performance/practicality won out for me. And it costs about the same as the GC matic w/ Brembo brakes, 1.99M.
