What is my actual build date
This is my C4--- registered Vin # 00521 is believed to be the very oldest 'daily driver' C-4 Corvette outside of the National Corvette Museum (NCM). according to the previous owner, he told me that C-4 # 00521 was built 1/31/83, the very 1st week of C-4 production, shortly after the C-4 'pilot cars'. .. I have a NCM reproduction of the window sticker and the build sheet.... can anyone tell me where the acutal build date is in the build sheet - VIN # 1G1AY0786E5100521 
http://http://www.gmmodernmuscle.com/fileup...uild_sheet.jpg Click that link to see my build sheet.... help me find this I need that info for a Car show display it looks to have a date of 12-16 in the #10 slot on the sheet would that be 12-16 of 83 this IS a LOW VIN C4

On my build sheet the date including hour and minute is across the top to the right of Bowling Green Assembly. The number 10 position on my sheet is a code for the front caliper.
I couldn't get your link to work, sorry.

I thought I saw that car listed on ebay a few months back. Doesn't it have the wood trim in the dash and a custom exhaust? Are you the person with the ZR1 that listed it or the new owner? Its definately an early C4 but there were 520 cars built before it, I would have to assume some of them are still on the road today but unless someone were to come forward we can't say for sure. Nice looking example of a very early C4.

My sheet is quite a bit different, not surprising since the car is 10 years newer. The area you are looking at certainly appears to be the date and it must be 83 since the production run started in January 83 and ended in July of 84 to the best of my knowledge. What doesn't make sense to me is the low number if they had been building them for 11 months??

Is there any data in boxes 5 and 6 of your build sheet?? It either didn't scan or there is really nothing there. I also noticed that you do not have any data in Box 24.
The one I have for my 87 shows two items in those boxes; a "DATE 87/117" and "TIME 14:55: In Box 10, it shows 0123732 and 05-11. The 87/117 is a Julian date which is April 27th. The 05-11 is most likely May 11th. In Box 24 of my build sheet, I have the entire VIN, the "Job Sequence Number" and the last 6 digits of the VIN.
The Julian date on my sheet is probably the date that the car was scheduled for production (the day that all of the data was entered into the plant's computer) and the 05/11 is probably the actual date of the start of assembly.
The date in Box 10 of your build sheet (Dec 16) would be the start of assembly. The 16th being relatively late in the month and with holidays approcaching, I would bet that the car actually rolled off the assembly line after the first of the year. I don't recall the production figures per day for 1984 cars, but anytime there is a new body/generation, production is slower than usual and there would be more frequent line stoppages simply because everything is still new to the workers.
As far as lower-number VIN's of 84's, I agree wth 96polovette; there were 520 cars before it and the chances are good that some of those cars remain and are driven. Certainly 520 is a low number but it would be difficult to make a statement that yours is the "oldest" driven C4 on the road. I seem to recall a statement in an earlier thread about this car about somebody having an '84 in the low-300 range and it is a daily driver.

i'm not sure if that date is correct for your vin # i have a build date of 12-23-83 and my number is #28394... i'm not sure how fast chevy was throwin the C4's out the door, the build date you gave is 7 days before mine... that would come out to about 3,981 a day, and 165 units a day
also it seems that the VIN is cut off on your copy you posted

the last digits are not relative to the actual build sequence. That is simply the # for THAT model year, within the entire GM empire.
now, with 1984 vettes being early 1984 models, I donno how much of that applies.

I think that date would represent Dec 1982, not 1983. You must remember that the early cars were being built in late 1982 but not sold until Jan of 1983 as 1984 models. The 1984 Corvette was the longest running production model year (17 months)in the history of automobiles, or so I have been told numerous times.
According to "Corvette From The Inside" written by Dave Mclellan, the Chief Engineer who led the design of the C-4, the C-4 was set to be an '83 but because of delays they first decided to call it a late 1983. Because production started after the first of the year (1983), the new car could be called a 1984. After alot of heated discussions about the uninterrupted Corvette tradition they decided to call it an '84 to reduce the paperwork by not having to recertify for the 1984 model year on U.S. government emissions. The book states that the C-4 went on sale in California in January of 1983 so it stands to reason that some C-4's
had to be built during December of 1982 in order to have them in California for sale in January. They were released in the rest of the nation in March 1983.
The base price for the new C-4's was $21,800. I highly recommend this book that Dave McLellan wrote. It is loaded with all kinds of trivia about Vettes and particularly the C-4 which he helped design. One thing most people don't realize is that the C-4 was initially designed as a T-top and late in the design process Lloyd Reuss "requested" that the C-4 be reconfigured to a targa without the structural tie of the T-top. Because of the fact that the whole structure was designed to rely on the T to lend support to the structure, all C-4's wound up with that aggravating body twisting that they have when the targa top is removed.

12/16 is probably correct. As far as certain boxes in the build sheet not having data, it may be that they did not collect data for those specific things and it's also possible that the assembly line workers wanted to have more data at some point.
I recall looking at the eBay ad and the statement about the low number. But there was a reply regarding another car with a lower production number. While you obvously have a very early 84, I still think it would be difficult to state that the car is the lowest production number 84 being driven. But that was what the eBay seller wrote in the ad. If I was the one buying the car, I would have questioned him about that statement and what his rationale/proof was.
It's just that there is no real way to prove what the seller wrote. Finding proof that the 520 cars before that are gone, either wrecked, salvaged, or have become trailer queens would be vey difficult to do.
In any event, you have a very nice car and I hope you are enjoying it. BTW, gold cars are
My 87 is gold and only 397 gold metallic 87's were produced that year.

Don't let people bust your stones about the '84! We aren't the fastest Vettes on the street, but how fast can you REALLY go before you crash or tick off the police.

yes its the same ebay car you saw the ZR-1 was the car photographed with it I have it now ( 3rd owner ) It was in New mexico Now it resides in nebraska It does have the TPIS exhaust, zr1 wheels and soon to have Grand sport caliper upgrades thanks for the compliment.......... There are some people that refer this as a piece of CRAP Turd-colored Slow-*** - Underpowered - most pathetic car ever built C4 (these people are in bellevue, NE .... they are members of GM Modern Muscle ( Dont become a member here they talk trash and live to put other down )
I like the gold paint and the crossfire engine a lot. It chanels air through the hood, it is the only year of C4 configured with that novel intake system. The engine compartment appears less cluttered without the airbox and intake up front. It is interesting they abandoned that configuration after only 1 year of production. I've always wanted a very early 84 model Z51 to go with my 96. If I could afford another corvette I may have bought yours when it was on ebay. One of the first things I would have done if I bought it would have been to determine whether the Z51 suspension components are original. It is hard to find an 84 Z51 that hasn't been softened or modified in the supension at some point. Don't let what anyone says about the 84 being inferior get to you, there is more to a great car than horsepower.
