If you want stress free quick sale, sell it to the dealer...but expect to get lest than half of what it sells for privately.
The only way you would get decent price on it from dealer would be, if you're also buying a new car from him...in that case he will try to reel you in by making it seem like you're getting a reasonable amount for your old car...
After that, he will just rip you off on the other end to make up for it..
Selling privately is little more hustle, but if you make the rules clear by the way you word your ad, you can weed out most of the tire kickers.
Highlight the fact, that you're not responding to lowballers and stick with it....really not that much work.
Since there are usually lot of "no shows", make sure that you don't go too much out of your way to accommodate their schedule...if they like the car they will adjust to yours.
This way if the buyer doesn't show up, you didn't just cancel something like your dinner night because of it and it's no big deal.
Preferably deal with cash only.
But as far as your original question is concerned, you can't suck and blow at the same time...its either more hustle and more money, or worry free but you end up paying for this convenience by getting much less.
This is pretty much how things work in real life.
