I worked in a large Chevy store in North Miami as a teen in 1970, Sark Chevrolet. The owner, Leon Sarkisian, had a black/black/black 454 Caprice Coupe with buckets for awhile, really cool classy car, and his brothers wife had a black 454 Caprice wagon. His nephew Chuck, had a black/black SS454 Monte Carlo. We sold a few 454 Coupe's, and several of the 454 wagons. One was a typical optioned light green/tan vinyl guts Townsman or Impala wagon, dog dish caps and fat blackwalls, ordered new by U.S. Sugar for a Corp. Director, but somehow it came in without air to the dealer in Clewiston, Fla., soooo that dealer dealer-traded it to us for a white 454 wagon with air, that we had. I did the dealer-trade myself, and that light green 454 wagon went to a couple from Canada that hated air conditioning, and they pulled an Airstream trailer with it. That couple had a '69 427 no a/c wagon, but they had a wreck down here, and needed a new wagon to get back up north with their trailer. I did the trade on a Friday afternoon and didn't have to bring the car in until Monday morning, that thing was a beast, I think I put 300+ miles on it that weekend...
... The dealership owner, was a VP with Chevy at one time, and we got some awesome cars as a result. One of the 454 wagons, had factory buckets/console. It went to an owner or manager of the old Castaways Hotel in Sunny Isles. We also sold a couple of 454 wagons that were used as tow cars around Mia-Hollywood Dragway, and another loaded one to a local SK boat racer. I seem to vaguely remember that the Impala/Caprice was rated at 345hp, the MC/Chevelle at 360, Corvette at 390??, but they were all the same engines?? not as rare as one would think.
