Audio needs sweetened. Handling isn't terrible but some response times seem to lag. Maybe allow a little more performance abilities like tune settings. I.e. tire pressure, turbo psi, cosmetics ,maybe even tire wear. I rate 5 because I'm a Gran Turismo nut. the tracks are well laid out. Being in control of the car by turning off the assists. I can't stand to have the car stop itself. .what's the point of ME playing then ya know lol More can bevdone here, but it's definitely fun. Best MobileSim
