My interest was piqued in the late 80s as there were a few Alfa's locally with them, notably a Red 164 owned by my best mates Dad with Red centres and polished rims.
Went to Cardiff Uni in 95 and regularly saw a Speed Yellow 968 like below which I thought was perfect and still feel the same now


I noticed in the Cayman post that it's still a cheap option but pretty much never ticked!
