UPDATE:Since a few days, I've got the car working in-game. You can download the beta version here:

This a little something (actually it's a rather big something) I've been working on for the last few days. It was sort of intended as a spiritual successor to Kaje's Blocko Car until the styling got out of hand, and is based on a slew of different japanese cars, mostly Nissans.
This is what I've gotten done so far:



Most of the body work is already done; I mostly have small things like decals and nodes left, and possible some proportion editing. There are however a few things I need help with:
* How do I add hands to the steering wheel? Do I just import the blockhead hands into the model and attach them to the wheel?
* Is it possible to make a custom sitting pose for the player? I've read a little about making custom player anims, but I don't know how limited this technique is.
* I also want to add some engine sounds to the vehicle, however the variant that the Box Train and Spitfire uses is quite primitive. Is it possible to read the wheel speed rather than the speed the vehicle is moving at, and is it possible to detect whether the movement keys are pressed?
