i have worked for a used car lot for more than a decade.....over the past few years we have purchased numerous stratus' and sebrings,they are both equipped with the same under carriage(such as motor,trans,....etc) they have given our customers very good service,there is a downside to both the 4 cyl motor and the 6 cyl motor,with the 4 cyl they last a long time well past 100k miles,though if not properly maintained with oil changes the motors tend to give a little motor noise around or shortly after 100k miles,they keep going but to some this is a turn off,now the 6 cyl motor is a little more serious,if proper oil changes with recommended oil hasn't been performed then it has a bad history of cause them to lose oil pressure along with an early morning motor rattle,do your homework if buying used,we are pretty extensive with ones we buy cause it can be a costly mistake
also any chrysler car is odd about needing the trans. serviced to avoid long term problems..and thats not just sebrings that is all of them
