If you like tint, you can also try that. My interior on the Beetle used to be horrible, even with the light tan leather. I went with Ceramic tint in both the NB and my A3 (A3 has black leather). HUGE difference.I love Beetles so much that I'll probably just deal with the leatherette, anyway. Maybe a simple solution would be to buy a windshield sun shade when it's parked outside in the summer. The base Beetle fits all my needs.
According Jaime at VWVortex, TDIs will have the beam axle.I've read the new Beetle will have two different rear suspensions: the tried and true beam axle for the lower trim levels, and a four-link setup for the Turbo.
Heard anything on what the later-arriving TDI will have? Sure hope it sports the four-link setup.
