You might want to look around at values a little more
There have been several of the lowered trucks recently selling for 30-50k+
I love them all...original paint clean, original patina, restored original, resto-mod, lowered, bagged, slammed to the ground, and lifted.
I agree that some do poor work on the frames and driveline angles/alignment and some do dangerous installations...but I also see that on lifted trucks, and also mostly stock trucks where people heat the springs or cut them improperly for a slight lowering jobs.
