The 230 model is one of my favourites. I just loved the steering. OK, so you had to press down on the 'wrong' side to turn, compared to how cars actually would lurch, but this ability to go around bends in your layout or on the carpet, coupled with free spinning wheels, made driving it a pleasure.
What I hadn't realised until a few minutes ago was that the 230 model comes with different window units. Some have lines for pillars at the side, others don't. It also seems that every black model has the lines but you'll find cream and cerise editions with either.
