Does this dealer take old cars in as down payment for another car?

Yes, that would not be an issue. The amount varies depending on make model and condition of the vehicle.

Yes. Their service department is great. They have really stepped up their game.

It probably depends on the make,model and mileage and condition when presenting to the banks.

Yes

I think you would need to call the dealership. It would depend on the year and the shape the vehicle is in.

I'm sure they do.

Yes, I have a good salesman at Bill Collins and his name is David Clark. I've bought several cars from him
