Based on OP's conditions of RWD, Not too Expensive, Easy on gas and new literally his only choice is a BRZ or FR-S. An entry trim WRX couldn't possibly go in there, but while their MSRP isn't terrible, they aren't known for their fuel mileage and they are known for high insurance premiums.
My daily is a Jetta GLI. Fun little car that was cheap, has enough pep and handling capability to be fun and has a lot of creature comforts. I get about 34mpg on regular fuel and it costs lesson than $30.00 to fill up.
