I have some old Popular Mechanics magazines most of which contain owner's report surveys.
I found some interesting results for the question "had any mechanical trouble."
Take a look:
Popular Mechanics, July, 1969
1969 Cadillac Eldorado
Had any mechanical trouble?
No------- 80.3%
Yes------ 19.7%
Popular Mechanics, Jan., 1971
1971 Mercedes (all models)
Had any mechanical trouble?
No------- 62.9%
Yes------ 37.1%
Not really surprising that the Cadillac had less problems, but it will probably surprise some people.
This is also interesting:
1969 Cadillac Eldorado
Specific likes:
Performance----- 22.8%
1971 Mercedes (all models)
Specific dislikes:
Lack of power---- 10.7%
