Welcome Richard. I think a majority of people like to see some personalisation. From your photos I can see your mods are tasteful and for one, I like them. At the end of the day it is down to personal choice and I have seen some shockers in the past that would make you cry. I think the thing about nodding to fellow owners etc depends on where you live. There are loads of BM owners around my area, most of which are company cars, so its very unlikely. However when I have seen an older style M3 or M5 in the car park I have often had a good chat with the owner as I do with most classic car and unusual car owners. Enjoy the Beamer.
