GT4 continues in its predecessors' footsteps by offering an extremely large list of cars; the PAL version features 721 cars from 80 manufacturers.
Players now accumulate points by winning races in the normal first-person driving mode, called A-Spec mode. Each race event can yield up to a maximum of 200 A-Spec points. Generally, a win using a car with less of an advantage over the AI opponents is worth more points. Points can only be won once, so to win further points from a previously-won event, it must be re-won using a car with less of an advantage over the AI. There are also the 34 Missions which can yield 250 points each. Despite this, A-Spec points are experience points, not money.
