The whole stigma about Miatas being "chick cars" is exactly why they will never be the "next Civic." I bet ricers are too concerned with looking girly, so they'll stay away from Miatas. Instead, they'll get Scion tCs.
THAT'S RIGHT, I SAID IT: The Scion tC is the new Civic. FWD, underpowered, overhyped, and cheap enough for anybody with a steady income to buy. Especially in the next 4-5 years as they get way cheaper, you'll see more and more of them riced out.
