We've been keeping something from you.
When FMU moved to Iron Gate almost ten years ago, not everything made the trip. Some cars got left behind in a storage annex at our old building. Customer projects that went quiet, shop cars we tore apart with big plans, a couple we grabbed because we saw potential. We told ourselves we'd get to them. We didn't.
Some of you remember Goldwheels. Some of you remember the Roadster spinning to 9,000 RPM on the dyno. Some of you have been asking about the RS6 for years. They've all been sitting in the same room, untouched, collecting dust.
Well, the landlord called. Everything has to go. So we grabbed a camera and opened the vault.
What's inside, where it's all going, and a major announcement about FMU's future that we've been waiting to share. It's all in this video.
This one means a lot to us. Give it a watch and let us know which build you want to see come back to life first. Link in the comments!
