White smoke posting car for sale how much?

[dard]

Here is my posting craigslist. What is the car worth now? i have the blue and black cap for the coolant reservoir.

THE PORSCHE HAS HAD A LOT OF WORK DONE AND I CAN NO LONGER AFFORD THE CAR. THE CAR CURRENTLY HAS WHITE SMOKE FROM EXHAUST SOME TIMES . THERE IS NO FROTH IN THE OIL OR COOLANT, HOWEVER IS WITH STEAM FROM CAP AND WHITE SMOKE FROM EXHAUST SOME TIMES. AS IS CAR NEEDS REPAIR, BUT STILL RUNS. THE AIR BAG LIGHT IS ON AND BEEN ON A LONG TIME, MAY BE SWITCH OR SOMEONE SAID UNHOOK BATTERY AND RESET IT. NOT SURE AND NEVER BOTHERED WITH IT. DRIVE SEAT POWER NOT WORKING NOW(MAYBE RELATED TO AIR BAG LIGHT) the windshield washer sprayer came disconnneted some how(sprays on ground) Fading to the carpet and wear to the leather seats as it is 15 years old.. there is wear to the interior of car

This is a very fun car and was my stress relief and I am the third owner of the car. The car in 2011 maybe hit a small animal and minor. Last year on my birthday, a kid swiped the driver rear panel with his mustang and was all repaired professionally.
1. The car looks pretty good for the years. People and friends love the look. However with finances it has to go and currently needs repair of some type and I do not have the time and money to have it diagnosed. It does run and drive and shift and all.
There is white smoke from the exhaust now and parked it. It did not over heat with the smoke and was like at 185 temp on guage. It does have pressure in the coolant tank with some steam from the cap sometimes. I had a lot of work done for thousands of dollars already and will list it all.
The car in the past year month has installed:
1) Replaced cup holders
2) new radio and new dash speakers(door speakers need replaced still)
3) oil change 0-50 oil and duralast additive. K&N air and oil filters installed couple hundred miles ago. New oil pan plug, old is fine but mechanic mentioned it.
4) new coolant tank installed. new valve and coolant cap replaced. Has steam in trunk still?OVER $800 spent on that...
5) LED lights for tag, doors, and both trunks...
Recent work done and repairs in past couple years:
1) recent water pump
2) belt
3) spark plug seals
4) oil cooler
5) LN engineering IMS Bearing retrofit cost $2500. see door panel for bar code proof.
6) lights buffed and detailed clear and clean.
7) recent battery
8) main large coolant hose replaced another $300 August 2015
The car A/C works, the top works fine, the power windows work, and the auto shift works. THE CAR IS BLOWING WHITE SMOKE FROM EXHAUSTSOMETIMES(they said I may need to take some oil out due to adding the big bottle of Duralast after the $150 oil change and oil seperator random squirt oil in exhaust..). I TOOK PHOTO OF TRUCK WITH LINER REMOVED TO SHOW CLEAN AND NEW COOLANT TANK. THE CARPET WAS BE REINSTALLED PRIOR TO SALE IN THE TRUNK(removed for replace of coolant tank). YES CAR STARTS RIGHT UP EACH TIME. AND RUNS AND IDLES AND NOT SHOW OVER HEATING.
****you are buying this car knowing it has needs to be repaired***** I am not a mechanic and do not have time to check it or repair it. I am a single dad selling things to make the bills and this fun ride has to go because I don't care to repair it anymore.***

Driving the other day ran fine, then puff of smoke for seconds out rear and then stopped after driving 10-12 miles.. Also note that the rear spoiler does not go up any more and the driver door sometimes relay does not fully unlock door, press on door click and open. it has a relay in door lowers and raise the window and unlocks door just maybe out of sync or something. It does not appear to be an issue when driving with window down and top down lol.
