I woulkd like functional stuff. I think a total set of well-designed underbody panels would be sweet. Flat underbody panels w/ a rear diffuser would ROCK.
This would take some knowhow and prob. some mimicktry (spelling?) or a ferrari or something but would be CRAZY sweet and add to the handling of our cars at high speeds. I'd drop some serious cash on one that was functional and looked good.
I also think interior pieces are sweet too, but nothing outside of OEM. an OEM dash would rock, as well as door panels. This being both for MKII's and MKI's. The MKI's are hard to find decent interior pieces for.
Most of all I want the underbody panels/diffuser. If you can get me a complete one of those that fits and bolts up easily, I'll even fu*k you for them
