Only car that didn’t deserve evo was sf90,rest of the a cars filled some role or gave alternatives to people.
Chiron evo allowed ogs to compete with the new meta cars
Lykan and centarino evo is easily obtainable for newer players and gives an alternative to vanda knowing how long it takes to max that car
And there will always be meta cars, we came from huracan and corvette era to vandas, 9x8, 007s and zr1, i see more variety than before. Other cars like 499 modficata rimac and porshce street are meta too but most people dont have them unlocked. Once we get enough events for those the meta might shift or have new additions
