To get the way my vehicle is you need to put in the ELS File.

To do this go to: GTA IV Directory/ELS Folder then drop the fbi file in there. Now to get that to work, you need to make it so the
ELS will go off of that for the vehicle you need to change the name in the slot control file(ELS 8). Go into the slot control and 
what ever vehicle you put my car under, you need to make the file in slot control the name of the ELS file I gave you.

For Example:

[ FBI ]
Status = on
File = fbi
