So you want to tune your Jetta or may be Bora. Tough choice! Well, you have to start somewhere. Anywhere you like. Just begin doing something. Buy a sticker or something :). There! You made your 1st step.
I came across some nice little thing over the internet, looks much better than the stock thing.
"Replace the common place factory "Fuba" antenna with an aftermarket replacement from JOM or FD. Machined from billet these high quality antennas separate any VW or Audi from the crowd. Simple installation requires no tools, unscrew the old and screw on the new."
Well. it's not some veilside widebody, but I think it is worth it.
