Some vehicle owners follow a certain time table, say, every 5 years from the time of purchase from brand new to the "ideal" time to sell a car. What most say is that this time frame is the best compromise between using the car to its optimal performance and still get a good price for it when sold.

Manufacturers, on the average, also change their variants in an "all new" package (which includes dramatic changes in body features and technological advancements) every 5 five years or so.

I think that it is sometimes unfortunate that some second hand car buyers let "brand mentality" rule over their choice even if there are a good number of well maintained Korean cars that can be obviously in better condition than their Japanese counterparts of the same age and category.
