Jalopnik says the Miata is the answer to everything. I may be here if you are not in need of a rear seat. You should be able to find an MR2 in that price range too.
If you need more seating...
5th or 6th gen Civic might be a good option. I'd avoid the 7th gen ('01-05).
Mazda3 is supposed to be fun to drive, but I've never had the chance. A first gen might be found in your price range.
You said reliable, so VW is out.
