by car/ by my car/ in my car

[optimistic pessimist]

Dear all,

I understand it's okay to say, "We went to the beach in my car".

What about the following sentences? Are they also fine?

1. We went to the beach by my car.
2. We went to the beach with my car.

Thank you!

You can say "by car" but not "by my car."
Don't use "with" at all.
