This is a 325i 4-door sedan. I purchased side markers from Umnitza and when they would not fit in the rectangular opening, they finally admited that they were for the earlier model and then edited their web site to show that the clear side is for a 1999-2001 Sedan or a 2000-2003 Coupe. They were originally described as fitting all E46s.
Note: be aware of inaccurate fittment descriptions - this is at least the 3rd time a sponsor's web site specified a model which later turned out to be wrong. You only find out after you waste time ordering it only to find out the vendor didn't know what product they were selling. I've always been able to return it, but it's a pain in the butt.
