I challenge you to show us an interior that's supremely blue. Good luck!
If one photo could sum up the entirety of 80s German tuning, you're looking at it. It's the interior of a Mercedes 280TE by Zender, and amazingly not a single Smurf was harmed in the process.
This is the Zender Vision 3. Hans-Albert Zender had six four-wheeled visions in the eighties. This appeared on the scene around the same time the Ferrari F40 did. It also remained a prototype.
