I'm Confused Regarding the "VIN" on this GS

    I am considering a 71 GS Stage 1 Convertible but am confused on the number on the car.

    434367FL1 000174 is on the data plate riveted to the cowl.
    4343671H 000576 is the VIN (in the recess on the dash top oriented so it can be read through the windshield).

    I know how to decode the first 8-9 digits which confirms the car is a 71, a GS, and a convertible that was built in Flint.
    BUT -- -- shouldn't the last six digits match when comparing the two number??
    Any help out there?

    Craig, the data plate is not the VIN and has no relationship with the VIN. It is the Fisher Body number used by Fisher for their internal purposes.

    Thanks for the quick reply. I knew there had to be a logical explanation.

    Craig

    Brad -- a follow-on question (since I know you have an unparalleled knowledge of GS's).

    This car is touted as being: ". . . reportedly one of 25 Stage 1 “zone demonstrators” built on August 5, 1970, all of which were finished in Cortez Gold over Pearl White vinyl and distributed to GM executives before going to dealers and the general public."
    Was there such a thing and is there a way to confirm this is one of the 25? . . . the VIN is pretty low.

    It could be, but I have no idea how you can prove or disprove. Very low VIN and body number, I will say. Many other folks on here with much deeper knowledge than I on the stepchildren (68-69's). What's the rest of the body tag say? That's a start.

    This is easier to read:

    53 is indeed Cortez Gold, the A is the top colour.
    TR 155 is for Pearl White interior on the GS convertible


    08E = Built in de 5th week of August 1970.
    (08 is August, A = week 1, B = week 2 and so on)

    From a video on YouTube:

    One of just 11 registry-listed 1971 GS Stage 1 ‘Zone Demonstrator’ convertibles, this Buick was a rare classic straight from the factory.

    Zone Demo GS cars were unique in two ways.
    For starters, they all sported Buick’s new-for-1971 Cortez Gold paint between White convertible tops and snazzy Pearl interiors.

    And secondly, they were pretty much fully-optioned rigs.
    Delivered to the Buick Zone Office in Jacksonville, Florida in August of 1970, this GS is 1 of roughly 25 Zone Demo convertibles produced for the 1971 model year.

    Craig, check the block stamping real close on that car. Several members have mentioned that it appears like it may be a restamp.

    Also, the dealer bought it last month at Indy for $55k plus commission, apparently is looking to get $90k for it.

    Thanx everyone -- especially for the link to the details on the Zone Demonstrators.

    Re flynbuick's comment (Someone added the GSX stripe scheme on the car later in life) it is my understanding that the rear wing was never added to the GS conv. The ad does state the GSX stripes were added by a PO.

    The bidding - with 3 days remaining -- is only at $20K.
    Not sure he's gonna reach $90K much less his $55K+ purchase price unless things really start to pick up for him.

    Agreed, I would be surprised if it gets past his purchase price, much less meets his reserve

    dynaflow shiftless...

    ...stock rear spoiler doesn't fit convertibles due to different slope of top rear quarters...

    Just to close out this thread, the auction really took off in the last hour or so and peaked at $49,000.
    No SALE.
