10220 is my favorite Lego model of all time (yes - it wins with every Technic set ;) ) - but it definitely needs some love to be something more than just a beautiful sculpture.
I would like to add suspension and steering - but I do not have any bulletproof solution for such a small space (picture of bare "base" - http://3.bp.blogspot.com/-c2sdXPLjFxw/TpfWQGZQUmI/AAAAAAAACO8/ARmir6mTTow/s1600/H88-Lego-10220-T1-Chassis.jpg - thanks to The Car Blog)
Has anyone ever made a Lego car in similar space with working suspension? I need some inspiration :)
