This just made me realize; with this update, including the Extreme E cars, we now have double the amount of cars that were in at launch. PG, over the last three years, have basically added an entire game's worth of cars, and since we know we're getting four more next update, that'll be about 873 cars and likely growing, since PG hasn't said if High-Performance Dailies will be the final content update or not.
Holy crap I am impressed with this dedication. We basically now have officially 33% more cars now than FH4 did when they pulled the plug.
