Car choices and Season Changes

Considering the $$ charged for the full version of this new Horizon, I’m disappointed in the car choices. This is mostly a rehash of cars from Version 3. Seriously, what’s with all the 2012, etc cars? 2018 is almost over and I see practically nothing new to choose from. The scenery is amazing for sure but this is a program about driving and I find myself driving and upgrading the very same stuff I did in version 3.
While I’m at it, how come the cars act and react exactly the same regardless of seasons. I can tear down a snow covered road at exactly the same speed as a summer drive. Season changes have to be more than just eye candy - driving game remember?
