I'm only in a civic atm, working my way up to a lude, before s200 and then NSeX... (that's my planned route anyway, though tbh I should have gone gran tourino instead of civic but hey, it's done now)
It's just a bit of fun...
It's free and you get to run a lude round your phone screen, that's enough for me!
(And I don't exactly see you do any driving in other driving games on phones either, so it's no loss afaic - anyone looking for me to think of modern computer games as anything serious or worth getting excited about will just be wasting a lot of their breath I'm afraid)
