when i was very interested in a car, he didnt seem interested in trying to sell it. i was even wondering if i was talking to a salesman. then when i call him to tell him ill be there to buy it, he tells me he'll hold it for me but DOESNT GIVE ME A DEADLINE TO BE THERE. i come there to buy the car and he already sells it to someone else. completely unprofessional people.
