Shameful self promotion here, try the 1999 Lambo Diablo GTR with my tune, it might be what you like or not. You’ll need the normal Diablo first, then get the GTR from the skill tree.
This game I liked the Supra GR so far, from previous games the Huracan Performante was butter smooth at 900.
But I’m in the same boat as you, I feel like most of the cars got dumbed down so you’re almost forced to put everything into S1 900, but then it’s very hard to find that car, or those cars where you have a golden child for races, a golden child for adventures, etc.
