Tbh Alan if I was you I'd stick with the standard kit, IMO the "se with an msport kit" has been done to death.
As said your looking at spending about 500e for what will be a rep front bumper at the end of the day. Probably 1000 for a complete kit.
You will also be doing well to find a s/h kit in Titan silver that won't need at the very least touching up.

I take it your 325 came with the exterior chrome pack? If so I'd be binning this in favor of black trim.
The e46 325 is a great car and with a few choice mods can be even better.

Put up a few pics
