grammatical number - Plural or singular noun when it refers to two things in a list


I wonder which of the two is correct:




  1. I have a red and a blue car.

  2. I have a red and a blue cars.



or




  1. Everyone has a left and a right arms.

  2. Everyone has a left and a right arm.



My (non-native) inclination would be for option 1, as it sounds better. On the other hand, in the following examples, the plural sounds better to me.



  • Everyone has left and right arms.

  • I have old and new cars. (when I only have only one old car and one new car)

  • The left and the right arms are...


But are they correct?
