Hi Dan, If your E9
originally came with them as an optional extra when the car was new (I believe BM sold these as an option on CSi's or a dealer could get them installed during a a later service) I reckon you should keep them on. Especially too if they are still in good condition.
Furthermore I think they really suit your car. The silver contrasts nicely will Fyord, and goes well with your 14x 7" Alpina rims too.
I know most people don't agree, but personally I think they are one of the coolest period E9 items.
(PS You could also fix those little bits of rust, treat and prime, then put the trim back on over the top. Saves respraying Fyiord for the 2 small the repaired sections)
