You sound like you are writing specs for a Kia Stinger to me. IIRC, Kia "poached" some talent from BMW re design/execution of this platform.
Please take my data point for what it is worth. My daily driver for a number of years was a 95 Jeep Cherokee with 90K on it as it belonged to my mom.
For any number of road trips, I rented a number of small sedans to include Toyota Corollas, Chevy Cruises, Ford Fiesta/Focus, Nisan Ventra etc.
My 2017 Leased VW Jetta is miles ahead of the other sub 20k offerings in terms of driving dynamics, even when hamstrung with a set of OEM tires that are optimized for fuel economy.
There is something about "German" engineering that positively affects the driving experience. JAD is spot on IMHO.
Keep us in the loop.
