Everything! The seats fold up for easy hauling, camping, etc. It can haul a lot for a smallish vehicle. I love the square shape. I like the uniqueness about it. I can put the seats in hundreds of configurations without needing assistance.
Lots of room, great cargo space, seats very adjustable. I bought the car new and never have had any major problems: just routine maintenance. Great for people with children. Waterproof upholstery that feels like fine cloth.
The only con is that the front seat belts are attached to the front seats. This causes the seatbelts to cut into your next sometimes while driving / riding. I know this was a change from prior models and I wish the seat belts were attached to the doors like before.
High step in, when the 2 back seats are up in the hanging position, hard to see to back up. This really is the only problem I see in the design. I cannot believe Honda stopped making this model. Also, I wish it got better mileage. Mine gets 20+ miles to the gallon.
The 2010 Honda Element has an average owner rating of 4.35 out of 5 which ranks it #5 of 27 other Compact SUVs.
