They come and go pretty quickly on KSL. I think I know the one you're talking about, those blue headlights are weird. Rebuilt title ISFs pop up all the time for under $20K - I think there's a silver one like that, 16K, looks great, low miles but unfortunate about the title. There was a real clean dark grey ISF for about 22K with a clean title last week but it's gone.
I guess 400+ HP and rear wheel drive is just too much for inexperienced drivers. So many rebuilt title ISFs out there haha
I could never bring myself to buy a Rebuilt Title. I saw those two awhile back both with Rebuilt titles. One will pop up eventually.
