I might be being a bit dim here, but wasn't there a section for BMW CSL's and CSi's etc. I am sure there was, or I might be having a senior moment here.
Given the large number of M3s for sale, it'd be great if there was a different section for E30/E36/E46/E92. Much like there is for 964/993/996/997 in the Pork aisle.
