Just off the top of my head:
I squeaked 31 MPG out of mine once.
It's quiet and smooth.
Really has a satisfying rush of power.
Inspect the front spring perches for rust damage.
Make sure it starts from cold without sputtering and knocking.
Check EVERY function of the climate control system - run the fan up and down manually.
Check the funky cup holder for proper operation...
If if has the CD changer, make sure it has a cartridge and check it's operation.
Make sure all 4 windows will auto close and auto open. Should just need a momentary press. I've seen a few cars that are out of sync and the owners don't know what to do with them but it's an easy, free fix.
That's all I can think of right now.
Also, check the classified section of this forum. Someone was selling one with less miles for about 9995 a couple weeks ago.
