This is if you want to try it out to modernize some of the vehicles with proper engine sounds, but, ONLY
Copy for the engine sound files, if you go to the RAGE Audio tool method. Or just copy & paste the sound
files, if you go to the FLA method.

ALT6: The Lokus with FAST_1: It's ironic that R* always put angrier V8s sounds on yet modelling cars with Inline-4 
or 6 engine blocks. While the ones with actual V8 models they always put some random inline-4 engine sounds, well 
this is one of those cases, that now it has the proper V8 sound that can fit pretty well for a getaway vehicle from 
an angry Russian Mob stampede with a VIP NOOSE politician on the back or as the getaway vehicle from the rats of 
the Waste management crew with a booty of 2 millions of dollars:

ALT7: If you didn't like my V_STYLE_1 approach for the Karin/Emperor Previon for the previous pack;
This is an alternative that now has the FAST_1 engine, if you like the Lokus powered-V8 sound conversion, 
so it can match properly as they're on the same family of Japanese V8 powered luxury vehicles (just like
the IRL rebadged Lexus vehicles):
