you need cd2 which is in .iso format, mount it with a .iso handler like
daemon tools or
power iso
once you have installed the .iso handler, right click on the tools icon/go to start/ programs/ and then whatever it says, something like mount image or set number of virtual drives.
then navigate to the rave .iso, right click and select mount image on drive (whatever drive number/letter)
once mounted then you can open the disk as you would a normal disk. click on rave.exe and you will be into rave, click the middle of the screen then your in 'carparc' select vehicle and browse to the section you need!!!
job done piece of cake!!!
just looked at mine, i'm using power iso, if you right click rave cd2.iso, select power iso then set number of drives, select 1(or more if you want) then right click it again and it will allow you to mount the image!
