Hi

I'm hoping someone can help me.
I watched a movie on tv about 10 years ago(i think) that had to do with a new American car manufacturer that was going to create a new car to take on the big three,i'm sure it was set in the 50's.
I know in one of the scenes the owner of the company took about 50 or so cars to court to prove that they worked.
I think he also showed he's son the plane that Howard Hughes built and told his son that dreams can come true.

Can some one please give me the name this movie.
Thank you
