1999 Mercedes-Benz S320 (V6) clean title

Selling AS IS The back of the car says S500 it's an S320 I don't know why but I bought the car that way 6 years ago Car starts and runs good A/C doesn't not work just blows out normal air The sunroof opens with no issue but the roof hooding interior is detached a little. I got new original spark plugs for the car but needs to be installed Needs to change coils Has 76,000 miles almost 77k The door locks do not automatically you need to do it manually Theres some what a little rust around the car Window doors sometimes automatically open and close sometimes you have to do it manually In all honesty I am selling this car because I can not keep up with it anymore and I already have another car.
