The Honda Odyssey can fit a bike (my Specialized Sirrus Sport (Large sized) ) in the back but you need to make some seating adjustments...mainly you need to remove anything in the center area of the van. Then you can just roll the bike straight down the middle and it fits perfectly.
I'm not sure you're going to find a car where you can fit a bike in the trunk WITHOUT adjusting the seats at all or taking off wheels...
