I don't know what car is sitting in my listening room, but I can say that the listening room in my car (truck) is amazing. I'm finding the sound quality of the system I installed there difficult to match in the home.
Kenwood (high-end model - nothing special there) head unit to Phoenix Gold MS250 (high-current from the 90's) to 3-way Morel (8-3/4" bass) separates in the doors, and Orion HCCA250 Digital Reference (also from 90's) powering two 12" Digital Designs subs in a custom enclosure (I built). I'm amazed how good it sounds every time I get in the truck. How can the system sound that good with the drivers 90deg off axis! Think it has something to do with the massive hex-core magnets on the mids and tweets. I have considered getting a second set of Renaissance Audio SR-8.3 and build some home speakers with proper air volume for the bass driver.
