This first-gen K5 got a full cosmetic refresh south of the border—metallic silver and gray paint, black and red vinyl—before bouncing through Arizona, New Mexico, and South Dakota. No Reserve auctions on these full-size square bodies pull real money when the details matter. Clean K5s are getting harder to find as prices climb.

This is the Impala SS that actually matters—the one with the LT1, not the 1994-95 pretenders. Black paint, 90k original miles, modified exhaust, and it's been in California since new. The 4L60E is the weak link everyone knows about, but the fundamentals are solid.
