What I do want is R* to add more cars with more reasonable content. Maybe mix them with new heists.
Examples:
A set of supers that ends up in Benny's? Well, make it the star role of a new heist that's similar to how Furious 5: with only that ridiculous fast car that can break the security system (somehow).
Weeny Issi Customs can do an Italian Job, escaping through the subway, and have Benny mod it to be versatile enough to dodge scripted heavy traffic.
We can help out the movie studios to reclaim some classic cars to be used in the movies, and relate that with Solomon Richards' stage in the main story..
Or even have precursor heists to Devin Weston's car collection that involve the new stock, then have a finale similar to what we did in Series A: hot transfer.
Then, we have a new sports classic that has to investigate and reclaim the Merryweather device that Trevor had his eyes on the story, but through a secret underground base, which involves us using said car, converted to a Bond-esque submersible to escape with in a quick fashion. But we're working with a Merryweather rep to steal it, ehh? Ehh?
Oh! Oh! And a set of missions that can unlock the Duke O' Death, but involves driving around Blaine County and messing with a drug/brothel operation from some real murderous people. Maybe the O'Neil brother's rivals before they dominated.
And then, we can have a Zancudo base infiltration, where we need another variant of the Insurgent with a nuke inside to..
Now I'm just rambling, I apologize
