I guess that can be useful, but the third line is a list of Peugeot models, not Renault. The real Renault line also misses at least the Zoé model, so I think you still need to work on your data a little bit.

Also, there's the problem of which old models have to be included, since there are both discontinued models that are included, and others that aren't: maybe it would be better to include production dates which each model?

Ah and I think you should take advantage of JSON's unique charset encoding to include accents in your data (like Citroën).

Sorry for the criticism, but I think your project would gain from a little bit more consistency.
