Why does it say that the model does not exist when I try to spawn it? I am sure that I have all of the addons required.

the man that made the model took it down

Sorry for not replying sooner but I was busy, my apologies. Regarding the model, the original creator took down his addons so it's no longer supported and I will be taking this down once you have acknowledged this message. Sorry for the inconvenience but I DO NOT own these models and I have no authority over them, it was only a collaborated project to utilize the original owner's vehicles and provide simfphys player base some interesting and well worked on vehicles. I would like to apologize again for the inconvenience and will be waiting for your reply if you have any questions.
