My favorite bike hauler that we sold was a Honda Element. I am so bummed that they are no longer made. I still see a lot of them around, though. They are really perfect for hauling bikes, though because of their boxy design were not good on gas. Since then we've had a Honda CR-V, which was okay, but we did have to remove the front wheels and put the back seat down if we didn't want to lie the bikes down on their sides (not a fan of that). We also really liked a Kia Soul we rented not too long ago. Those tiny cars have a lot more room inside than you'd expect, and the gas mileage was great. You can easily carry a bike (front wheel off), but once again will have to put the back seat down.

I hope you find what you're looking for!
