Pretty self-explanatory. Lowrider variants of the Gavril Barstow, Burnside Special, Gavril Grand Marshall, Bruckell Moonhawk, and Gavril D15. As always, they're in the vehicle selector.
Sorry, I have zero experience in stuff like that. Also, just a warning, these configs are basically useless now, as most of them are included either Djplopper's or NinetyNine's config packs.
