The tech's a little low, the dashboard's a little cheap, and it's a little light on power, but the 2013 Subaru BRZ is still an absolute treat: probably the most fun that you can have in a new car for under $25K. Alternatively, you can choose the mechanically identical
Scion FR-S, if you really like orange paint, or the
BMW 135is, if you've got money to blow.
