Personally, I think buying privately is the way to go. Through my personal experiences I have found cars from private sellers are generally in better condition overall compared to dealers. The prices are also slightly cheaper and you get to know what the previous owner is like so you know how the car's been treated.
The price of that car seems slightly overpriced but it looks okay from the pictures. It is best to get a closer look in real life as pics don't do justice.
Good luck with the hunting!
