I would say a large proportion of the owners on this forum mod their cars and take them to the track. Of course they do; it’s a forum for enthusiasts. (And a few moaners
) I would also say though that in general, the number of owners who do all that is very small. I have only seen one modded 2 series in the UK in four years (frozen wrapped), and the UK is the third biggest market. We buy nearly as many of them as the Germans!
