Soooo… it is just shy of 5 years since the original post and I have learned a lot in that time period. The 1967 300SEb was purchased new in 1967 by my great uncle. He took delivery of it in Stuttgart in June 1967. Hy cousin (his daughter) offered me the car in 2006, and in November 2021 I FINALLY picked it up. The VIN is 10801512002509 and it still has the original M189 engine with the Bosch mechanical fuel injection system.

As some individuals noted, the mechanic that had looked over it in the past was somewhat clueless as to what needed to be done. After getting the car, I found an amazing mechanic (Bob Kunsak from RK Industries). He spent a lot of time with the car addressing the engine performance issues. As it turns out, there was nothing wrong with the Bosch system at all. The car now runs flawlessly with full power.
