I don't know if I'm going to do any mods. My dad doesn't like mods for some reason. I might get K&N filters, maybe an exust. It is an automatic though, and my dad doesn't want to replace a fine trans, even though it doesn't go into reverse, but that will be fixed in several days.
As for handling, my brother already tested it. His car was down, so he had to drive the 323. I went with him to several places, and coming up to a light, he wasn't paying attention, and saw the red and slammed the brakes. All wheels locked(no ABS), and the car stopped real quick. We also went on a highway, and got of via a clover leaf exit. speed limit on it was 25, we went 50(my dad never goes above 45 in his probe, so this was pretty fast. It made it though the corner, which with my brother is a good thing.
It's a great first car.
