If you can afford it, stretch to a new model ( 2001+ STI )
The regular cars are no comparison. The STI has better brakes, beter suspension, a far superior gearbox, better engine. Everything is worth the extra.
The base models cars brakes are barely adequate, gearbox isnt very strong, and generally a much cheaper car.
If tis just a daily commute, they are fine. But if you want something to drive and enjoy, the STI is far superior, and will take a lot more abuse and tuning.
