Each car in Forza Horizon 4 has its own unique 'Car Mastery' skill tree. As you drive a specific car and perform skill chains, you'll earn Skill Points. These points can then be spent in that car's Mastery tree to unlock various perks.

Car Mastery Perks Include:
- Influence Boosts: Earn extra Influence from specific activities.
- Credit Bonuses: Receive bonus credits for races or skill chains.
- Wheelspins/Super Wheelspins: Often found at the end of a mastery tree, providing valuable rewards.
- Skill Score Multipliers: Increase the rate at which you earn skill points.
- Forzathon Point Bonuses: Earn extra Forzathon Points.
- Car-Specific Perks: Some cars have unique perks related to their type or manufacturer.
Investing Skill Points into your favorite cars' masteries is a great way to maximize your rewards and make your most-driven vehicles even more profitable. Prioritize cars you use frequently or those with particularly lucrative Wheelspin perks.
