I see yer pernt, but at the same time, there are many that can't swing that much time off so close together. In my case, being retired, I could, but still wouldn't just because they're too close together. I'd just be needin' my fill of the real 24, having already seen many of the past cars realtime back in the day.
Don't get me wrong, I enjoy historic racing, but enuff is enuff within so little time. Anyhow, clk....enjoy....
