        Hi Gang
        Most Cabriolet’s have that elusive number that is not recorded anywhere in the Archives at JDHT.
        I was told many years ago that it was the Body Number. But as we all know that starts either 5Y00 or 5V00 and is well hidden under the rear bumper. It does not relate to the number off the Line.
        So what is it / was it for. Have you worked out which number I mean? I bet most of you have never seen it.
        When I ask most Owners they say there isn’t one, then a few days later oh I have found it.
        Yes that’s the one in the rain gutter of the Boot / Trunk. Left hand side Fwd of rear lights.
        I was told by a man who worked on the production line at the time, now Curator of Vehicles JDHT (can’t remember his name, Lots of E’s & F’s) that there was a little man who looked After the body shells & that he stamped them, and it was his way of stock taking. ???????
        So if you can locate it. Please get in touch or if you have another version Of why it’s there feel free.

          Hi Laurence!

          I first didn’t think my car had the elusive number, but after a thorough check I found three digits, i.e. 620, barely visible under the new resto paint from 2013. I’ve tried to take several photos as proof, but none of them are convincing. Unless later photography will give better photos, you’ll just have to take my word for it, or better yet come to Spain to see for yourselves 🙂

            Thanks Stig.
            How long has it taken you to find that out.
            I have just discovered that Stephen Tebben USA & Braham Lieberman Australia have consecutive boot numbers.
            Braham #1794 build date 15/10/1985 Car number 1113
            Stephen #1795 build date 19/03/1986 Car number 1802
            almost 5 months later and 689 Cabriolets separates them so you can see how erratic the marking was.
            Steve’s other one is #2351 Build date 23/06/1986
            Of the Cabriolets we have located 1,836 we only have 265 here is a reminder of where it is located

              Dear Bleasie,
              The elusive number on my cabriolet is 1143. It is an 86 3.6 5-speed (vin 126155), one of the few “gray market” 3.6 cabriolets that made it to the United States. Please let me know if you need any other info.
              Thanks, Tom

                        Hi Bleasie,
                        Mine looks to have 5036 stamped in it (hard to tell as the paint has filled in a lot of the first and third digits).
                        Cheers, Ian (VIN 147465)

                            Hi Ian that looks pretty realistic nearest to your #5062 and #5047

                                      Hi Gang
                                      Responding to the Elusive number game
                                      my XJS Cabby in metallic red with reg number E739NVT and vin as per photo has the number 4151 on the nearside of the boot gutter
                                      Regards Mike Hampton (of Aldwick Bognor Regis – not many Cabby owners south of us in UK!)

                                      PS I tried copying in from WORD two photos of the 4151 and the VIN but it did not want to accept the photos from a WORD document. I have no idea howto include those so take my word the VIN is SAJJNACC7CA142922

                                        My car, has 1770 as a lucky number:
                                        VIN = 131892
                                        Body = 5V 2103
                                        And there’s another number, on the opposite side of the Body number: 2JB27D 0413021
                                        Any ideas?

                                            hi bleasie

                                            got a weird one for you

                                            my 3.6 cabby has the boot gutter number 1451

                                            however the 4 has been overstamped with a 2

                                            therefore it could be 1251

                                            does this make it worth millions like a misshapen penny black or just a typo from the bodywork man

                                            cheers eddie

                                              Sorry not worth any more

You can also get a rough idea at A previous owner may have logged your car in their database, or you could browse a VIN range to check details for cars either side of your VIN. Warning – the browse functionality can be inconsistent.
