You are definitely on your way. My first recommendations would be the grills, painted reflectors, tint and angel eyes.
If you are looking for some body components, all of the Vorsteiner E92 M3 parts can be installed and removed without any permanent modification to the vehicle. At the moment, we have the front spoiler available for the sedan, the rear diffuser will be available later this summer.

I'd also recommend some interior upgrades like our Interior Xenon Bulb Kits
and the new Vorsteiner CF Interior Trim which will be available in the coming weeks.
