That's been pretty much the standard, at least since the Spec II update.
 
It appears the Legendary Car Dealership has been expanded. There are currently 19 cars in there. Perhaps someone stumbled across an old barn full of classic cars and this is a one-month thing. :lol: I guess it remains to be seen, but a welcome addition regardless.
