I would agree scrap. 6311 is sitting outside under Yukon across from Costco. The fire appears to have been in the engine - a/c area. I passed by there before and also appears to have a bent frame from the rear to the roof.
Staten Island vandals used to cut the wires for the push tape bell, and the air assist rear door, so ones which had been really messed up were changed to pull cords for the bell and some had the back door air assist fixed/modified.
According to BusTime, last night, MCI 2770 was on the S62. I've been on a re-routed X15 which was sent to the ferry one day when the Gowanus was a total mess due to an overturned truck. Was quite a sight to see MCIs there.
