E92 restomods · built by hand

The last great analogue coupe. Finished properly.

We restore and re-engineer 2007–2013 E92 coupes by hand: naturally aspirated V8, hydraulic steering, and none of the things that broke the first time.

Strip-down

Every car comes apart to the bare shell. We media-blast, measure and photograph it, then fix what fifteen winters did before a single new part goes on.

Owners

In their words

“I've owned mine since 2012. It came back feeling the way I remember it, except now nothing rattles and the brakes are astonishing.”
Daniel R. · Build 019, Signature
“The weekly photo log was the best part. I watched every bolt go back in from the other side of the country.”
Sofia M. · Build 024, Commission
“They talked me out of two expensive options I didn't need. That is why I trusted them with the rest.”
James O. · Build 030, Refresh

Why we only build E92s
