If you do not want to run the 24 hours yourself, you can use you B-spec driver. I searched for some older threads which might give you more information or help on your questions:
"24 Hour race?! Let's discuss please XD
"B-spec tips and info
"24h race, should I a-spec or b-spec?"
"Using B-spec and its potential"
I hope you can find some answers 👍
Greycap explained you how to get the Toyota 88C-V car, which is, except for the Formula 1 car, pretty much the fastest car in the game.
You don't have to wait 24 hours, you can speed up the race by going into the B-spec menu when your B-spec driver is racing, followed by holding "L1", and pressing the right or left button on the D-pad, depending on how fast you want the time to speed up. You can speed up the race to 3X. If L1 + that button doesn't work, than it's R1, at the moment, I'm unsure wether it's L1 or R1 since I haven't done a 24 hour race in long while...However, when you speed up the game by 2X or 3X and the driver comes into the pits, the time slows down again so after each pitstop, you'll have to manually speed up the time 👍
A different alternative would be to let your B-spec driver run the race, go to bed and go to school the next day or whatever fills your 24 hours and the race is done! Your PS2 should easily be capable of running 24 hours non-stop, people have already proven this point, both the older and newer PS2 models 👍
Good luck!
