changing starter on pt cruiser??

i haven't looked at or seen the car i was asked to change a starter in yet,but it's a cruiser,around 3 or 4 years old,just how easy is it to change the starter in it?,,i don't know about certain modifications in different years or if thier all pretty much the same,can anyone tell me if removing exhaust,or subframes or other componets are a factor?? thanks,i know this isn't much info yet,but anything would be helpful to see if i should even look at it,
