Big no from me, even dispite my (untrue) reputation on here as a Toyota dick rider. 250k on a former taxi car for $5,500 that you'd have to travel to even look at sounds horrible. There are plenty of better cars to be found at that price
As someone who's stupidly driven far distances for what looked like a good deal on a Used car, I'd never recommend it to anyone. Way too much pressure to buy at that point (sunk cost fallacy, I know), that you overlook issues you'll regret later
