I am in the market for a used car and stumbled upon this Escape. I showed it to some friends and they said it looked a little shady since it has a new engine and so many miles. I called the owner and he said his daughter ran the oil out and ruined the old engine. I was going to offer him around $5500-$6000 since $7700 seems a little high. My friends thought i should offer him $4500, but that seems low. Does this seem shady or maybe not bad?
