The story
I bought this 2020 M340i xDrive wrecked — real accident damage, not a scratch-and-dent special. The price was right because the work ahead of me was serious.
Instead of sending it to a shop, I’m rebuilding it in my own garage, one weekend at a time. Every repair, every mod, and every receipt gets documented here and on the Johnson Motorsports channel.
The goal isn’t a trailer queen — it’s a properly sorted G20 I can drive hard with confidence, and a record of exactly what it took to get there.
