In regards to the 911;

Purists would say that the 911 started in 1964 after being re-named the 911 from the original Type 901 which was launched in 1963. The 911 concluded in 1988 with the last year of the 911 Carrera 3.2L car. Then the Type 964 followed in 1989 and the various other Types thereafter (993, 996, 997, and 991). So, 1964-1989 or 25 years.

Generalists would say that the 911 has been in around the entire time from 1964-2015 (51 years) and many would include the original 901's (52 years).

Which ever way you want to count, its been around a long time.
