I'm looking for a replacement car by the 30th of September, but I'm having trouble finding the perfect one. Wondering if you guys could help me out...

Must:
* be $20,000 or less
* be fairly new (no older than '99 or so - financing)
* have under 50-60k miles
* have adequate power (160hp+)
* have a manual transmission
* have at least some cargo room
* get at least 20mpg city
* be reliable

Prefer:
* $15,000 or less
* run on 87 octane
* get at least 25mpg
* have aftermarket support
* luxury (leather, power seats, sunroof, etc)


I'm open to everything from an Audi TT to a Mustang GT convertible to a Saab 9-3......
