Just look at the top vehicles directly, look at the vehicle introduction of WRC or World Touring Car Championship, and then split the inquiry separately. Study hard, go to Invincible Modification Network for three hours every day, and search for vehicle modification cases under various vehicle conditions. If there is a modified auto show, you must redeem and subscribe to OPTION magazine to buy a car with great cost performance and modification potential.

In addition, I often go to the library to consult books related to automobile technology to avoid common sense mistakes.

I hope I can give you some hints.
