This is a follow-up of a 6 stud wide 2-seater vehicle concept I made a while ago, as seen here. I've actually built this many months ago, but never really bothered to post it until now. I've seen many similar designs lately, so I suppose it's not that interesting. Now, the real challenge would be making a 5-wide 2-seater. It's probably impossible... unless the minifigs have no arms or something.
