I have a Subaru Outback. It gets about 22-25 mpg and the newer ones are even better. When I take one bike (mine) I just leave the back seat down and it slides in without taking off the back wheel. We have even stacked 2 on top of each other with a piece of cardboard in between. With 3 bikes, you would need a rack of some sort. See if it's big enough for your BF. It's a great car that has not had any problems, and I bought it in 2004.
