This is just my personal opinion...
I don't like the Reiger kit, but I agree that your exterior needs some work to bring your car to life. These are pieces I found, that aren’t' that expensive, that I think will really help the look of your car.
1. Projector head lights
2. European clear lights
3. License plate delete
4. Black out grills
5. Color match bumpers/rockers (or re-spray car)
6. BavAuto DTM front lip spoiler.

I found all of these parts (except head lights) on BavAuto
