Agree on the debadge, did it on my 1.6 FSI and makes the rear look cleaner and more discreet!
Other mods you can do:
~ MK5 Polo Stubby Aerial.
~ Colour Coded Rear Valance (Clean look or twin exhausts (GTI/R32) though the latter will need extra work on a 1.6 FSI).
~ Facelift the front bumper to the GT,GTI or Jetta style which imo makes the frontend a bit more aggressive!
~ GTI Sideskirts to go with the rear valance and frontend.
~ Rear Dewipered.
~ Lowering Springs or Coilovers for extra lows or Airride if you have a big budget!
~ Upgrade the 15" wheels to something a bit more bigger.
~ MK6 Golf Chrome Light & Window Switches.
~ Cherry Red Hazard Switch!
~ Upgrade the standard stereo for a MK6 RCD/RNS double din stereo to keep the factory look... or go aftermarket.
~ GTI or R32 Seats!
~ Projector style headlights
~ Tinted rear lights, or get the LED version and convert it for RHD.
~ Wrap/paint the centre console for a fresher look.
There probably loads more you can do which I haven't mentioned! But enjoy the car!
