Welcome! I think one of the problems with reverse engineering a photograph, is that it isn't necessarily teaching you how to develop the sense of understanding and constructing the 3D form because you are trying to match the photo which already has foreshortening and perspective built into it, but trying to use constructive techniques at the same time.
I wonder if perhaps taking or making orthographic designs first, and then using the techniques in that book to transfer them into perspective would be a better workflow to start with? By using orthos you will be able to properly measure and test your transformations into perspective rather than wing it from a single perspective shot. If you do want to just essentially copy a photo, definitely make sure your guides are accurate and identical to the original or it will be a pointless exercise.
Also consider starting with less complex objects to build up your confidence and workflow first. Those cars you chose are difficult because of the curving forms. Consider doing things with simpler primitive shapes first. A kids wagon, a train etc. You can't fly before you can walk. Well you can, but you will go splat soon after.
