Yes, the concept works and there is not much the companies can do to make just their car unique in design. The Rb5 and B4 are very similar but still different in characteristics on the track. Think another 2wd from any company will look like those available already unless the go for a mid motor kit which I hardly believe they will.
I don't care if it is a copy of another car. Or is it is really fare to call a rb5 for
a copy? I don't think so. A bike will always look like a bike have done for the past 50 years or so. If it is not broke...
Think the quality speak for it self. Would love some blue aluminium on there though
