First time poster. My parents sold their almost new car to my DB for a big discount a year ago.
When visiting DP recently, DB and SIL show up in a new car. It turns out after DP asked them that they had sold the car my DP sold them (at a profit) and bought a brand new car.
AIBU to think they should have at least mentioned it to DP, or offered to sell the car back to them? They have effectively made a profit off a kind gesture from my parents. Either I or DS would happily have bought the car off them (and are considerable less well off than they are) if they told us or DP they were looking to sell it.
