Where is best place to sell or get the value of a 1975 Buick LeSabre and should I sell it as is or invest in a refurbishment?

sounds choice~...put it on the market and some homies are gonna put Wheels and obnoxious stereos on that and destroy the original beauty~ The motor ain't locked up, is it? a running one would bring you at least $8000~....Buicks are sought after by the homestyle community~

I'd restore it back to it's original condition, then sell it to a collector~
