Here is a converted from LS 15 BMW X5 for download. The 15er model was from clrsjohn (thanks again for the release)
In addition to the conversion from the LS 15, I changed the following:
Co-driver script for up to 3 players
admission script
IC for doors, hood and trunk. Driver's door can also be opened with R from the outside

I wish you a lot of fun with the mod!
The mod may also be shared on other sites, but please only with the original download link!
