Using "stack up"

Hello,

Can I use the verb “stack up” the following way (from a native speaker’s point of view)?

  1. I was stacking my car up against my friend’s. It turned out that my friend’s car was better than mine.
  2. We were stacking our houses up against each other. We couldn’t agree on whose house was better.

Thanks!

I would say these are a more natural usage:

I was comparing my car with my friend’s car. I wanted to see how they stacked up.

We were comparing houses but we couldn’t agree about how well they stacked up against each other.

Thanks Bev!
I see your point.
