looks like you beat me to it, BUT
my corrections are in the above chart. (in Orange
That is why I asked.
The 250C came originally with a 2.5 L motor and only in 1969 was also offered with a 2.8 L.
then discontinued (in the US) as the 280 C came out..
check the engine number (or if your VIN starts 114 021 or 023)
250C 1st version had the 2.5L M114.920 motor (8,824 produced)
250C 2nd version had the 2.8L M130.923
motor (and of which 10.527 series1 & 1,241 series2 were Cs)
250CE had the 2.8 L M114.98
0 motor and 21.787 were produced) total= 41,138 C & CEs.
The 250 sedan had the same paralell, 77,000+ produced with 2.5L motor and about 34,000 with the 2.8L M130.923 motor)
The 280S (W108) had a similar motor, but not exactly the same M130.920
It was also in the 280SE/L with the M130.98
0 designation, but those were fuel injected.
How is the video coming along ?
