You know, if you want something similar to the RX-7, The Scion FR-S/Subaru BRZ is actually a well put together car. You'll hear people gripe about their lack of power, but they're missing the bigger picture of amazing handling. They're nothing like the FR-S or the RX-7, but the Ford Focus and Fiesta STs are great cars in their own right.
If power is your thing though, and you still want something that's a bit more practical price wise, the new Mustang is hard to beat. Though, I'd probably wait until the 2016 or 2017 model year comes out, so Ford has a chance to work out the first model year kinks.
