I have never driven a car by Ford. Have you?
Yup, I drove a Ford Fiesta for a while. Ford's a good quality brand, they've been around since June 16, 1903.
I always think quality with Japanese cars. How does Ford compare? How are they rated>
I'm not sure but Ford branches out to other countries. they own 8% of Aston Martin in the UK and 49% of Jiangling in China.
I have never heard of Jiangling. Is that a popular automaker? 
I don't know that much about it. It is one of the many Chinese car manufacturers like Beijing Automotive and Brilliance Automotive.
How profitable a company is Ford? I know the US auto industry has had problems in the past.
I'm not sure,, but they have manufactured tractors in the past so I'm sure they are doing well.
Do they no longer manufacturer tractors?
Not that I'm aware of. They made tractors and their components in the past.
