If you want then you should consider this first:
Im on android and can get up to 450< parts but no more than that, xml is allowed such as making the engine even stronger, except that engine must be at least at a level where it still realistic (aka no 200000hp), must be a sedan or a hatchback or liftback (you choose), sponsors (included as part limit) is allowed, no active suspension and active aero, maximum speed of around 365< (5km/h tolerance), all cars will be raced at Gold Prix Raceway with no restart except when checkpoint missed or car aero damaged, no AI control because... You know, AI's..., i will drive it, preferably throttle and roll system and last but not least be creative and create your own Silhouettes
