+1 on the RAV4. One of the reasons we bought it was because of the fold-flat seats coupled with it having the largest cubic feet of capacity for carrying your gear/bikes (in the smaller SUV crossover world). On the test drive, we brought it home and stuffed a couple of bikes in there to make sure it would work. We have easily fit 3 in and I imagine 1 more would fit fine.
