Best car for under 5,500?

I thought I would have 7000 for a car and was lookin forward to an eclipse GSX but no.. Not exactly in the budget right now I need something for under 5,500 and I want all the speed I can get. I was also hoping to fit 4 people in the car though. SO far I have been looking at the nissan 240 SX and the Toyota Celica GT. Both of these cars seem reliable and good but I wanted to hear your opinions.. or if u have another car to suggest that is great 2. thanx in advance.
