STis are very responsive to modifications...especially with tuning.

The Evos can be reliable, but buying a used one can be tricky. You need to check everything on them. You don't want one that was improperly abused. Does that make sense?

Also, the 6 speed in the MR isn't that great. Evo owners have been swaping out the 6 speed for the 5 speed. The sad/disappointing part is that the 6 speed was supposed to be the saving grace.
