I got an angle from the front and here's a side by side comparison of the real 3.2 CL Type S (left) and the one in game. Apparently, the Sundace Gold colour scheme you see here is pretty rare with only 900 existing according to a couple of sources, so not only was I treated with this Acura, but the amazing colour as well!
Since it's one of the many cars in the series that's never seen the light of day being remastered in modern graphics, it's quite jarring to see some of the details being textures and/or pixelated to the oblivion lol. But mind you, Gran Turismo 3 came out in 2001, so the huge leap in graphics were impressive for its time! Credit goes to Bug for the in-game photo!
It first caught my attention when I saw the back of this car. The red 'S' is one thing, but its taillights is another. I gasped and almost wanted to tear up when I got closer. In the game cover, it's colour blue and has a rear wing but is the exact same car aside from that. Again, take a good look at the taillights!
For people who still have doubts that it's the cover car of the game, the physical game manual (remember when they used to do that?) has a credits section where the devs thanked Honda for being able to use the Acura 3.2 CL Type S. Again, credit goes to Bug for the photo.
