For Sale: 1974 3.0 CS Coupe
E9 Forum thread with description and pictures of work performed.
I purchased this coupe in 2014. Shortly thereafter I enlisted forum member Sven Larsen to help with an extensive engine, suspension and driveline rebuild and upgrade. The old 3.0 carbureted engine was exchanged for a 3.5 fuel injected custom built engine with MegaSquirt 3. Paul Burke custom cam and custom pistons. The goal was to upgrade but keep the car looking as stock as possible.

https://e9coupe.com/forum/threads/driveline-suspension-engine-redo.17451/
Color: Granatrot
Mileage: 126,000 – 4,500 on new engine.
The new engine is amazing! She’s fast, pulls really hard in every gear with a beautiful and aggressive exhaust note.
Below is a list of the work completed over the past 4 years and while she’s certainly not a perfect 100 point car I feel she one of the best maintained driest and fastest coupes out there.
Car will be available for purchase through BaT auction site in coming weeks.

The car is as close to rust free as I think you can get these days without a ground up rotisserie and while I don’t want to say 100% it’s close. I believe it spent its life in California, and Arizona before moving to Seattle.
