We use basic tools of descriptive set theory to prove that a closed setof marked groups hasquasi‐isometry classes, provided that every non‐empty open subset ofcontains at least two non‐quasi‐isometric groups. It follows that every perfect set of marked groups having a dense subset of finitely presented groups containsquasi‐isometry classes. These results account for most known constructions of continuous families of non‐quasi‐isometric finitely generated groups. We use them to prove the existence ofquasi‐isometry classes of finitely generated groups having interesting algebraic, geometric, or model‐theoretic properties (for example, such groups can be torsion, simple, verbally complete or they can all have the same elementary theory).
