Grand Am for 2004 includes sedans in SE and uplevel SE1 and SE2 trim. Coupes and sedans are available in sportier GT and GT1 guise. SE and SE1 have a 4-cyl engine and manual or automatic transmission. A V6 with automatic transmission is standard for SE2 and available for SE1. GTs have a "Ram Air" V6 with slightly more power. ABS and traction control are a $400 option for SE and SE1, but are standard elsewhere. GTs have rear disc brakes vs. drums on other models. All Grand Ams have satellite radio as an option. Grand Am shares its basic design with the Oldsmobile Alero, which will be dropped after the 2004 model year. Newly available for all models except SE is an MP3 option that upgrades the existing CD player to read discs recorded in MP3 format.
