Sellin a car = bullshit

one approach to car selling: place ad with good honest description. give plenty of good pics. when someone calls , simply answer the questions asked. agree to send more pics of any part of car in question. NO other conversation. if they ask a question already fully addressed in the ad, politely refer them to ad.
when they come to look. bring car out of garage. tell them to look it over as they wish. then go somewhere else. tell them where you will be if they need you. DO NOT have any conversation with them, simply answer questions. IF they buy the car, then participate in conversation. and hopefully make a good friend.
too much conversation on the sellers part will usually result in saying sometime that need not be said. IE : I want to sell because: I need the $$$, my dog is sick, lost interest, tired of buying overpriced Mopar parts, pissed because my bodyman screwed me, wife wants a new sofa! ETC
we all know,, the seller would always like to sell high, the buyer always wants to buy low. its a lot easy to sell a car that is priced under the market than over. and what a person has invested in his car, has NOTHING to do with its value, unfortunately.
