I'm a bit stuck here. Since your and my are followed by a noun and yours and mine are not, the following sentences should be:
- I'm standing between your and my car.
But this seems really wrong. Yet, with yours and mine it reads better but it's wrong too:
- I'm standing between yours and mine car.
I know that we can say:
- I'm standing between my car and yours (or "your car and mine")
But I'd like it to be like this sentence:
- There are his and her clothes in the wardrobe.
Edit: With his and her i can see two meanings:
- Clothes that belong to him and her alike.
- Clothes that belong to him and clothes that belong to her.
