I'd say that my least used map is basically any stock map because of FPS reasons. Also, my least-used car would have to be the T-Series because it's so BIIIIG and it doesn't really want to drift.
Any map except Gridmap. I play all cars. My favorite challenge is to try to jump the water at gridmap with all configs
i like all the cars exept the super low down ones, i dont really like the new template map as it isboring
