I don't have the PC version unfortunately, though I do have two copies of the PSOne version (one isn't mine). Just did the car park, and took me just a few tries (haven't played the game in years) and got past it. Here's a PC FAQ:

And also, on the main menu, under Training, pick Car Park and it shows you how to do all of the moves you need to use including to pass.
Order I did them in to pass:
Handbreak+Speed (Nail both at the same time)
Reverse 180
360
180
Burnout
Slalom
Lap
Was at about 53 or 54 seconds when I finished the lap, because it took me two tries to get the 180 right and I'm slow at the Slalom :-/
