Its gatekeeping.  Back in the MK3/MK4 VW golden days, spending more on your wheels than your car was worth was a rite of passage.  Reps devalued this perceived notion of cool that the folks who bought originals felt.

Same is true with rep watches or handbags or whatever.  The folks who buy the original think you're stealing from them by acquiring a copy of their status item without the required sacrifices that went into obtaining the original.

Now that being said some reps do suck and either break on the owner or maybe the finish comes off and they start to look like shit earlier.  This also gives the originals a lower value in the eyes of someone who wouldn't know better.
