I still have quite a bit of work left to do in the garage. The lockers are used for basic storage of a few things - cleaning stuff, tools, etc. (The main house garage is on the opposite side of the wall for a 2x2 layout)
I'm on the hunt for a Z4 and M3 hood that I'll have painted to match the current colors, they will hang on the wall where the lockers are now. Under the hoods, I am planning to put a engraved blueprint of each of the engines under the hoods - see here:

The lockers will move to the opposite wall along with a larger industrial steel table that will be refinished. They were moved there for now as the home builder wanted several pictures of the house for a showcase they were doing. Lots left to do.
