Price-wise, the base on MY2020 went up $500. But then some of the packages are lower (2019 Premium + Convenience is $4950 while 2020 Premium Pkg is $4700. Also Park Assist Pkg went down $200).
I'm about to take delivery of a 2019 330i (it's at the VPC now) and it looks like a comparable 2020 with the same options is $50 higher
