How do I determine production numbers?

[stuckerdud]

I have a black on black 1990 convertible with most of the options that were available at the time, including FX3 and the 6-speed. With that combination, I think the car might be quite unique given that 90s are unique C4s with the 84-89 exterior and the 91 and beyond interior.

How do I determine how many cars were made with the combination of options that I have? I imagine that this is not a question that is easily answered but I have to start somewhere.

Thanks to any and all that have any insight.

google

Google "1990 corvette production"
Go to "Corvette action centre"
Go to "production and performance"

That tells me how many cars with each individual option were produced and appears to be the same information that is in the Corvette Black Book. How do I determine how many cars were produced with this combination of options:

1. Black exterior
2. Black interior
3. Convertible
4. FX3
5. Six speed

Thanks for any help you can provide.

stuckerdud... first off - welcome to the Corvette Action Center!

As to the production percentages you're looking for, one must "extrapolate" those percentages by a method much like a S.W.A.G. :L

I'm tired so it will take a few minutes to figure but let's see what we can come up with.

Bear with me here..........................

Raw data:

1990 total production - 23,646
Convertibles - 7,630
Black Exterior - 4,759
Black Interior - 4,977 leather sport seats
FX3 - 7,576
6 speed - 8,100

I have the leather sport seats. BTW - A guy I know has an '89 just like mine with an automatic and his driver seat started on fire while sitting at a toll booth in Detroit. He was on his way to fly a trip (airline pilot) and was in his uniform. His interior got covered in extinguishing agent and he got a new interior. He missed his trip.:L

Okay... here we go. And remember, this is only an estimate at best. :L

In 1990 there were a total of 23,646 Corvettes produced. Of that total, there were 8,100 6-speeds. That's 34% of the total production. There were 4,759 Black Vettes produced. So the number of 1990 Black Corvettes with 6-speed can be calculated as 34% or 1,618. The total number with Black interior (leather sport seats) was 4977 which is 21% of the total. So an extrapolated estimate of the number of black 1990 convertibles with 6-speed and black interiors is 21% of 1,618 or ~340.
The total production for the RPO FX3 was 7,576 or 32%.
So I'd calculate the number of 1990 Black Corvette Convertibles with Black leather sport seats, 6-speed and FX3 to be 32% of 340 or approximately 109.

My brain hurts.
