Curious to know if my 87 Aerocoupe, with a trim tag date of 3rd week of December was built early or late in the production year. . I sent away for the original invoice and it came back with a 12/18/86 build date. My sticker on the driver side door is worn away and could not be read. What are some of your build dates? Can we figure out when the 1987s Aerocoupes were actually built? Were they built from mid of 86 into the 1987 calander year? Is there a database with build dates that can be referenced?

I'm not sure but my SS rolled off the line at the end of February 1987. So yours is older than mine.

Aren't there two build dates for Aerocoupes? The factory and then the ASC build?

Possibly. Every date code or found on various components are within days of each other in February (door card was 2/26) and the invoiced and shipped to the dealer on 3/6 with an ETA of 3/13. With that I'd find it hard to believe two separate build dates with dates that close and the extent of modifications.
Maybe GM held off on stamping the 87 year until the conversion was completed..

A December build should be an 88,I think the 88 cars were all built before the end of December, most of the time, the build year began in August of the previous year. Unless you mean December of 86!!

Good call - I assumed Dec of 86 not Dec of 88. I seem to remembering that all 88s were finished in 87. Dont remember where I read that though.

So I guess my Aerocoupe was built as a mid production with a invoice date of 12/18/86. My son and I went to Mecum in Kissimmee this past January and We did find a Aerocoupe with a door tag built date of 07/87. I wonder when the first 87 and the last 87 Aerocoupes were built? If you have a 87 Aerocoupe and have a build date please leave a reply. Thanks Tomh115 for the build date reply.

Thank you for posting the build date of your 87 Aerocoupe, I think it would be interesting to see if someone has the first or last 87 Aerocoupe ever built.

I'm curious too, I didn't think there was any real set time period when the 87' Aero's were made during the model year but instead made throughout the year. 86's were a short window where that was documented a bit better, IIRC. The 87' I had I don't recall the month on the door jamb, the VIN ended with 126823, if that helps give a range of the build date.

All g-bodies stopped I think on 12/11/87 for production, so none were made in 88', but they were made in the 88' model year of course. Regals and Grand Prix's were called 87's due to the new w(?) bodies while the Monte name didn't continue and the Cutlass was called the Cutlass Supreme Classic for the 88' models. I know Monte's and Regal's were made through the end, I assume Cutlass and Grand Prix's were built until that point or close as well.

I checked and my door jam tag is so faded I couldn't read it, but the VIN ends 139142. I think I have the original window sticker and sale, I'll look there later.

My car rolled off the assembly line at the Pontiac Mi. plant on June 26 1987. I had heard some time ago that this G body plant ceased production in late November 1987.
My vin is 151411. I have my original window sticker as well as the broadcast sheet for my car. I am the original owner.

My car does have the “This car was altered by Cars and Concepts” sticker on the drivers side door jamb. Were all 87 Aerocoups sent off to Cars and Concepts to have the conversion done? My car was built at The Pontiac plant on 12/18/86

Yes, all Aerocoupes were born as notchbacks. C&C did all of the conversions. 200 86's. 6052 87's.
