I do so othen and it certainly helps with getting your reaction time a little better in a slower car. Put me in the bf1 or fo8 or fzr and I am more stable than if i was in the uf1. Never give up on any certain car and if you want to be near a wr it will take dedication and determination once we are at a stage where it seems we cannot improve.
Finally if its online racing then the cars you use depends on what servers are active
