Best racing game, period

Had this app for a long time. Tried many others, still think this is the best. Ive advanced far into it without spending a dime (as opposed to Real Racing which will frustrate and bankrupt you, thanks to the robber barons EA).
Its a fun game with near flawless controls, many tracks and many buses. I like that some of it is on pavement and some on dirt - good variety. Winning is a challenge but doable, and banging on or spinning out your opponents is an extra kick. Ive had some close, exciting races. I must be playing an earlier version. All the reviews complaining about ads, theres none in mine, I just play (lets keep it that way, ok?).
