We argue that the recently introduced “statefinder parameters” (Sahni et al., JETP Lett.77, 201 (2003)), that include the third derivative of the cosmic scale factor, are useful tools to characterize interacting quintessence models. We specify the statefinder parameters for two classes of models that solve, or at least alleviate, the coincidence problem.
