we buy cars sold me a broken scooter and covered up that the engine is broken

purchased the scooter and started it at the seller’s premises, where it appeared to run normally. Once I got home, I discovered that all the engine oil had been completely drained. I refilled it, and it required an entire bottle to reach the correct level. When I started it again, the scooter produced continuous heavy smoke. It is clear that the oil was intentionally drained so that the excessive smoke would not be visible during the initial startup, and to conceal the fact that the engine is severely damaged. Unfortunately, this has left me with a scooter that is effectively unusable, as repairing the engine is not economically viable I might as well buy a new one. This has been a hard lesson learned. - this place needs to go bankrupt
