2000 Ford Taurus

2000 Ford Taurus 150k miles, pw, pl, cd, runs and drives but has a misfire on cyl 2..says it needs a coil pack. no power steering. the heat doesn't work either but it does get up to operating temp and stays there just fine so I'm not sure if it's a plugged heater core or what? clean title.  Asking $500 FIRM!
