Does seem like a pretty nice deal unless the flooors are all rusted out or something. I'd pay that much for a solid Riv GS in a heartbeat if it was within a reasonable distance.
Its seems rare to see any buicks around i work in Enfield and live in West Sprinfield and i think i can count on one hand the Buicks i have see in this area other than my 68.
There's a guy in Easthampton with a 70 Stage, a 72 SCO 455 convertible and a 65 racecar......but he's kind of a jerk.
