Can anyone give me the best source to find the true private sale value of my 2019 Honda Civic with 13,828 miles on it? Or perhaps one of you has access to whatever resource dealers use to determine value? I need to sell it rather quickly. Are any of the online places like Carmax worth going through? It's silver, 1.5 l turbo, vin SHHFK7H86KU206403, perfect condition. Any help would be greatly appreciated.
