I deleted most of the default police vehicles I could find but I still have an Impaler, Dorado and another default vehicle that is spawning in traffic and as backup/at the PD's. All of my vehicles in the Emergency tab on my trainer spawn fine, just have defaults in traffic and as backup. I found one of the vehicles in the mp2024_01 folder and tried to delete it in OpenIV and got a "SYS_ERROR_00000005" unable to delete. Any suggestions on what to do now?
