This continues the trend of this car's immediate needs: neglect-induced maintenance. Often times folks have suggested "do a swap", as the RS platform is a popular candidate for such a project. However, there are leagues of work that need to go into this car before something like that is attempted. Stopping the spread of rust, re-doing exterior and interior portions, and pinning down worn-out parts before they cause a problem is the main focus for now.
I think, once the work has been done for the "save-the-car" portion of this project, there will be a clear path as to what direction to take things from there. Regardless, the work going into the RS now is coming along nicely.
