I think I've found my muse 

It's rather a long beast - any suggestions on how best to alter the proportions to keep in line with the general CK footprint?
Any suggestions on software that can quickly rescale an image based on, say wheel diameter??

I love your inspiration car! You have an excellent profile picture of the car to work with, so you have a great starting point to scale and downsize from. Start with the wheels and tires you will use or cardboard patterns of them. Place them against a wall at the proper wheelbase you will be using, then draw a paper or cardboard pattern on the wall adjusting the length of the hood, frame, tail and seating area until you have a shape that works well for your visualization of the car. This also allows you to adjust the ride height and seating/floorpan location to help with its center of balance. Plan on too much seating area, it is easier to make the seating area smaller than it is to make it bigger.
