OCD got the best of me...I couldn't "NOT" clean up the worn area.
Since nobody seemed to have any thoughts or comments, PM me if you are curious how I did this. I'll post two images (before/after) of the worst area. I only "spot-repaired" it. I left the passengers seat untouched and spot-repaired the worn spot in the lower cushion too.
I'll give the dye a few weeks to cure, vacuum storage bag the sections, bubble-wrap them and box them up for a future day. Unless anyone has ideas of what "not to do" to store these, this is all I could come up with on my own. Maybe it is "taboo" to "cheat" (preserve a driven car) like this, is perhaps why nobody responded yet, idk...but for me, saving the original upholstery AND enjoying the car while preserving it as much as I can, it seems like a good idea to me at least.
