sounds pack updated for ATS Classic Cars pack by Jazzycat v 2.6:
my mod must have higher priority in the mod load order.
in addition with my Real Traffic density mod
you can make classic cars as separate type of vehicles with own spawn rules by simply renaming the sii file from def/vehicle folder (base mod) into traffic_storage_classic.jazzycat.sii
with this modification classic cars will have individual spawn rules from my traffic density mod and you no longer need other mods than my sounds and the base mod
