Used MacBook Air 6,2 (Mid 2013), 4GB RAM, 256GB SSD. Clean install of Big Sur (11.7.4). Belonged to my Dad and he clearly took care of it, case is in good shape. Original SSD has power on time of under two months and is in good shape, 183 cycles on the battery so it might be OK for awhile and of course when connected to power you don't have to worry about battery life (comes with 60 watt MagSafe 2 power adapter). If you want a new battery I could put a new one in (I'd order from iFixit) for $85 on top of the winning bid, plus time to order and install, but at 183 cycles it might be worth waiting a bit.
