Wow !!! 21 friggin actual miles. That's almost a hard story to believe. I'd want to see the documentation where his dad bought 2 the same day and validate that story.
I would believe it, but that's me. I would also believe most of the rubber seals are shot and the gas tank is internally rusted. Only keeping a couple of gallons in it leaves a TON of room for condensation to get in there and start rust.
If my dad did that and I got the car, I would be frickin' driving the damn thing! Makes me wonder why this guy is trying to sell it. Is there known "problems" he is avoiding fixing to push onto the next owner? Or is he to egotistical to drive a 89 Celebrity? He probably thinks just because it has low miles everybody will want it. When in reality only Retro does! (jk) I had a 84 Celebrity with a carb'd 2.8 (I think?!). It was actually a good vehicle to me. Bought it for $200, put 50k miles on it, and sold it for $250!
