This is Gran Turismo 4's infamous Mission 34, in which the NTSC version (which is used in the Americas) is significantly harder than the PAL version (used in the rest of the world) because the wait at the start is eight seconds longer, at 123 seconds. My run at it is completely clean by standard Online Racing (OLR) rules, which mandate no AI contacts and keeping at least two tires on curbing or track at all times. It's obviously not perfect, especially considering how I had to coast behind the 300SL for a while at the end in order to avoid contact, but it's definitely a good run. I used a standard DualShock2 controller and manual transmission.
