Just stumbled on this and was wondering if anybody uses it ? seems to be pretty comprehensive at least as far as performance goes. just thought I'd pass it on. if its redundant and has been mentioned before I apologize.
https://www.automobile-catalog.com/

 

I have used it a lot...but, it was met with ridicule, here, when I posted it. Fake news, I reckon.

 

It's a third party site. That's far from the top of the credibility list. In order of credibility:

1) Factory literature (and yeah, I know there are documented errors in some factory literature,as well as cases of items that were planned then cancelled after printing of the document)
2) Period magazine tests (again, it these are not perfect either, and sometimes manufacturers gave them ringers).
3) Well researched books from credible authors (yeah, I've crapped on the Sullivan book before...)
4) Everything else

 

I love it and since I am a stats and specs nerd use it all the time. However just like Olds faq, etc, you should take it with a grain of salt. Your gonna wanna verify info before you swear by it. ( i have seemingly found mistakes...)

In the end as Joe P pointed out above nothing is perfect. We are human and these things are put together by humans. I agree with his list also, but the nice thing about Automobile Catalog is its sorta a one stop shopping for certain info and I commend Pawel Zal for it.
