If you don’t want an suv and want space, get a station wagon.
Amen. While not exactly a sedan..THIS was my rig Back in early 2000's. (Painted myself). 89 Ford Crown Vic Wagon.

PLENTY o Room, and then some.
Wagons are the most practical of all the vehicles Still. SUVs are really just smaller (than my example) /taller Wagons.
After that it was (2) Older Jeep Cherokees 89 & 90.
Then a beat 89 Chrysler Minivan.
89 Toyota Pickup
89 Ford Taurus SHO (Oooh, sedan).
02 Nissan Xterra, Plenty of Room
02 Subaru Outback WAGON.
2016 Jeep wrangler JKU (4 dr) 3.6 [NOT RECOMMEND] Ok room, sucky mileage, and at 104K "The Death Tick". .
I'm also in the market for a 'New' vehicle, btw.
All these vehicles handled an SWR Goliath III 410. by the Subaru Outback, I had switched to 2, 112 cabs, and now one Mesa SW 212 cab, which fits in the POS Jeep Wrangler Easy Peasy.
Point is a 212 SHOULD fit in the back seat of most modern sedans, if it doesn't fit in the trunk.
BUT, an SUV (Tall Wagon) makes it MUCH easier, not bending to lift something out from deep withing a sedan's trunk.
YMMV & all the things..
