I actually like the wood on mine. However, I was thinking it would be cool to do it in carbon fiber too if I ever go with my non stock interior idea. I have beautiful woodgrain pieces right now and would not hack them, but some of my other sets are ugly and maybe I will experiment on them.
My custom idea: Recaro seats from a 80's BMW 325 ES or a 1990 VW Golf GTI or Jetta GLI ( $15 each at the U pull it), split fold down rear seat from VW Passat ( German seats> American seats), center console with rear A/C vents and cup holders from a 2000 Cadillac ( saw it on E-Bay) and, of course a 3rd pedal and a chrome Hurst shifter poking out of the floor and attached to either a T-5 or a T-56. 🙂
