DB Car Sales

After taking a car for a test drive with my parents. I told the owner the car felt very sluggish and asked if a service could be offered for a sale to go ahead. He shot me down with an instant No. I then asked if my parents could have some one take a look at the car. Again an instant No. With out going into the full convo of politely asked questions. He went on to say to me. I don't fucking like you. Your a fucking knob head. Get the fuck out. What a sales man. Thankfully the car will remain his. With what I can only assume has many issues. The guy is a joke. Please be careful. He is an aggressive bully. Who didn't like being questioned. Very very sad little man.
