Thread: 1971 911S ? Help number matching confused!

  1. #11
    Noting the printout you've provided, the generally accepted practice on our early VINs is that the fourth digit indicates the model year. And for the engine, the third digit is the model year. Hope this helps!

    Verify where the information is coming from: info from Boschen and Barth books (The Porsche Book - a definitive illustrated history) will have the listing with the starting year of production to talk about the next model year.
    Germany for decades published the calendar year for when the car was constructed. So cars could be manufactured Aug - Dec of one year and Jan - July of the next, but being the same MODEL YEAR and in some cases tallied by which calendar year it was made.

    Lostreasure's example reads like it came from Lothar Boschen & Jurgen Barth (Germany).

    Look to the little white "Porsche Technical Specifications" book for the most accurate info.

    You're getting great advice from the experts on the forum to tread slowly and verify, but your replies seem to indicate that your mind is already made up. There are several VIN locations and the hidden production number above the ash tray. It's your money, but you should verify accuracy as there are a lot of unscrupulous folks out there.

    The chassis numbers were 9 digits starting with 11 until the 1970 model year. 70 and later had had 10 digit chassis numbers starting with 911 the 4th digit is the year model, not the year the car was made. The 5th digit is the engine type. 1 = T, 2 = E and 3 = S. The 6th digit is the body version, 0 = Coupe assembled by Porsche, 1 = Targa and 2 = Coupe built by Karmann. The last 4 are the sequential numbers. Its pretty simple. No, I don't get my info from the internet.

    What could possibly make one think that this car is anything other than a 71 car with a 70 motor? Yes, I would be very suspicious of these numbers. They look pretty janky to me. What redline is on the tach? Is there evidence of a factory oil cooler? The car should have an aluminum deck lid and sport seats, too.

    Regards

    Good point! 70 911s had the fuel pump in the front attached to the cross member. 71 had it in the left rear and the mount served as the LR sway bar mount. as well.

    And a bad joke at that since it perpetuates false information. Unfortunately there is a ton of such bad information floating around.
