I was reading an article about better speakers and such for the stereo in the 05 Imprezas. It is from a source in the Canadian market, but I imagine that the US will see similar improvements.2005 IMPREZA: What's New?
Model Line Up-Changes:
For 2005 the main changes to the model line involve the 2.5TS and 2.5RS sedan and sport wagon. For 2005 the base car (sedan and wagon) will be renamed to the 2.5RS. The 2.5RS will replace the existing 2.5TS sedan and wagon as the entry level model for Impreza sedan and wagon, however the level of equipment will remain similar to the 2004 2.5TS. The 2.5RS wagon will have 16" alloy wheels as standard equipment.
There will now also be a 2.5RS "Sport Package" sedan that will offer several of the features of the WRX STi and WRX. This model takes the place of what was the 2004 Impreza 2.5RS. The 2.5RS "Sport Package" Sedan will feature the STi type front bumper with fog light covers, side sill and rear WRX spoiler. It will also offer a leather wrapped steering wheel, aluminum sport pedals, sport seats (WRX type), a center mounted tachometer and an upgraded audio system and a power glass moonroof.
There are several new colors added for 2005:
Crystal Grey (All models except Outback Sport)
Regal Blue (All models except WRX and WRX STi)
Obsidian Black (All models)
