I ordered a new Corolla sport and it should arrive in januray 2005.
I had one Sport on a test drive for a day. It has originally "6-speakers" , a 2-way system front and also speakers in both rear doors. I listened many different CD's in that car and in my opinion it'll go fine. I was surprised from the sound quality, cause I wasn't expecting it to be so good. OEM speakers aren't for "Bassheads"

, but for a normal everyday use they're just fine. Of course there are some differencies between countries, so I recommend visiting a local Toyota dealer. There you'll be able to test the difference between those audio systems.
