Unfair to the average buyer, nothing new to the followers of the trend.
You search for a 240sx with the options you prefer, such as a manual transmission. Now comes the disappointing part, the lowest asking price for the car specified is $3000, a large jump from the true value, and a classic case of "drift tax".
In this case, the inflation is due to the fact that the Nissan 240sx is a very popular car in the drifting "scene", praised by fans for it's "capabilities". But most often you will find that these cars do not appear to be anything particularly sporty in stock form, with some you even might consider them to be nothing but eco-boxes dressed up to appear as something they aren't.
"Drift tax" varies in different parts of the world, the West Coast of North America is notorious for high inflation. Keep in mind that this does not only reach out to the 240sx, but almost any popular RWD Japanese sport compact.
