I sold mine private a few weeks ago..without boring you with all the details, I had 3 viewings over about 3 months then 2 viewings in over a week, the latter bought it.
On each occasion I had the car detailed in advance of the viewings at much expense (I like to use the car so there was always an element of work needed before it could be shown).
The first chap loved it but got all out of shape when he noted the front bumper had been painted.. another chap had another to go look at (after shaping my whole weekend around him), another said he couldn't pay it for 3 months, another still sorting his finances out waiting on a house sale etc.. infuriating.
All this amongst jumping through hoops with hundred of email, inspections, take it here pick it up again, clean it again, afternoon, weekends etc..
Add to this folk that DO NOT KNOW HOW TO DRIVE wanting a test drive in your £50k motor. I had to endure all sorts of driving styles. One guy, he was the type that dropped down a gear or 2 needlessly before every bend(?), he liked to go round bends with the engine at 6000rpm?? He approached a bend at over 50mph and put my 911 turbo in 2nd gear. what the hell for? He also crunched my front spoiler on a slope with doing a U turn. There are no words.
Other test drives equally as painful as folk fumble about looking at switches instead of the road. awful..
That was enough.. It fine for a 3series BMW daily driver but I will think twice doing it again with such a fast expensive car.
Funny though, the actual guy that bought it gave me the least hassle and was in and away within an hour start to finish. Compared to the others with all the questions and hoops to jump through.
I have sold every car I have had privately, but next time.. I think I'm getting too old for that stress and time wasting. If a dealer can get me the same money I will be open to that.
