I looked at all of those production charts, and the numbers don't add up. It doesn't give any numbers on 71 RR's with a 340, or 383 with a 3 speed manual.

I know that Galen Govier would be able to help me out with this, but just wondering in this day and age of fingertip data, is there anywhere online (even in book form) that has the production data on our cars with the different options and colors offered? I'm looking at what appears to be a 1971 Plymouth Roadrunner sassy grass 4 speed 383 with an air grabber. Build sheet, body VIN stamps, & FT are all there - seems legit, but now I'm wondering how rare is this car? I know you never see these kinds of cars for sale, so I know off the bat it's super rare. Is there no other sources of information other than getting on a list and hoping a verification of your car occurs within one's lifetime? Besides, how good is his information anyway - where did he get it? Who's going to question his appraisal when there seems to be very little out there to begin with so as to say that your car is 1 of 337 because of this or that? I'm not bashing the guy, I'm just asking the question - how good is the information that he brings to the table when it really cannot be verified anywhere else? I'm just talking production figures that I've seen on some of his appraisals now - that's what I'm talking about here.

At any rate, if anyone has a storage of knowledge out there with this information I would love to know where it is and be able to review it - mainly for my own use of how rare this or that is.............any ideas where this Mopar Valhalla of information is? I know that the the Shelby guys have their registry - and there are so many registered that most, if not all, of the existing cars are in it and verified having this or that. Other than Galen, is there any other registries for our cars, whether they be A, B, C, or E bodies? I know it's a lot of work for any of this stuff, but it would be great if there was something out there that I'm missing so I can help myself out.............

We have percentages for each option (the roadrunnernest link) but I have not found any information that lists how rare an individual car with a specific combination of options is.

the percentages are figured on TOTAL build numbers.

Super rare? By today's standards or GM / Ford standards yes. By Mopar standards no.

There were 3,730 manual trans 383 RR's for 71. The vast majority will be 4 speeds.

Of those ~5.5% were Sassy Grass green so that gets you to ~205 cars

Gotta take issue with this.



More RRs were built in 1971 than GTOs. Break any Brand X down and you'll find that they are as rare as Mopars – even Chevys on occasion.



You can't combine production numbers, like what Ken said above. While I don't know where the 5.5% came from (source?), presumably it would be for ALL Road Runners built. Hence, it would be statistically incorrect to use a percentage based on a sample (total RR production) and apply it to a smaller group of cars.

It's probability. It's a guesstimate.

I looked at all of those production charts, and the numbers don't add up. It doesn't give any numbers on 71 RR's with a 340, or 383 with a 3 speed manual.

Chrysler did not track option combinations.

One that is statistically incorrect.

Wait for some of the other members to chime in. They can help you out with production numbers although it's still not clear to me what exactly you're looking for. Is it how rare the 1971 Plymouth Roadrunner are by colour, 4 speeds or by Air Grabbers? depending on how you cook the numbers, anything can look rarer than it actually is. If you want to know about numbers using all 3 of the criteria just mentioned, just wait for some of the big Boys on here to chime in. All I can give you is perhaps numbers of 440+6 and Hemi cars and how many were 4 speeds vs automatics stuff like that or total Satellite production data with numbers by model. Some one will answer your question(s).
