Put the back seats down. In my Ford edge I slide my BK9 in and keybaord stand next to it. On my R&R cart I stand both up with bunge cords.
You can't buy a subcompact car and then have to figure how to get your equipment in. When I had biiger equipment I actually took a demop car home to see if everything would fit. Although I've see pics of guys putting their Hammond Clones and mini Leslies and other stuff in sub compacts its just too much hassle.
