No, it wasn't.

This question was a little challenging, but it all comes down to one thing, which is that neighbor's opinion. Everyone has their own opinion. Though it seems like this neighbor was letting his cars collect in his yard, it wasn't like the sight was that distasteful that it was such an eyesore.
