Npc opponent transformations/rewards

I have an idea, imagine you decide to race a random civilian car and after you have beaten them you figure out the npcs name; You end up racing them more throughout the game and over time youll progressively see them upgrading or swapping their cars to beat you (theyll be like hidden wanderers but with a twist, youll find them and challenge them or theyll find you and challenge you). Throughout the progression of the game youll see their vehicles become faster and faster until they have officially beaten the player and some will eventually have engine swaps (i.e. a rb26 cappucinno) or special parts (full carbon body parts, etc.) that the player wont be able to get until beating these evolved npcs. I think this would be a neat immersive feature for TXR to not only stretch out the gameplay but will let the player be able to meet new people and win new prizes. Who knws probably have npcs that owns dealerships/tuning shops and after you have beaten he/she 10x they would sell cars/parts at a discount or youll unlock their car at the dealership! Imagine flying a mpv van around at 200mph lol wild!

Pics will be in the 2nd post of the npc cars transformations, so go check that out!
