Hi,
In his books, Roger William's attempts to estimate the number of TRs still around. I don't know his sources. He doesn't say if he means running or not, or delve into their condition in any way. In some instances he tries to guestimate worldwide, USA and/or UK numbers. In most cases he adds pretty accurately known production/export (from England) numbers from factory records.
Here goes:
TR2, 1953-55: 8638 produced/5182 exported. Estimated 2500 remain worldwide, 1800 in the US, 600 in the UK. (Note: His US number seems very, very high to me, just based upon what shows up at typical British car meets.)
TR3, 1955-57: 13,377 produced/10,032 exported. Estimated 1700 worldwide, 900 in the US, 600 in the UK.
TR3A, 1957-62(I question his ending date, I thought it was '61): 58,309 produced/52,478 exported. 9500 survivors worldwide, doesn't break it down but the bulk were exported to the US, which is where most would likely be found today.
TR3"B", 1962: 3334 produced, all for export. 250-300 estimated to survive today.
TR4, 1961-65: 40,253 produced/36,803 exported. Estimated 4000 worldwide, 2550 of which are in the US.
TR4A, 1964-67: 28,465 produced/22,826 exported. Best guess, 4000 remain worldwide, of which 2500 are in the US and 1400 or so in the UK.
TR5, 1967-68: 2947 produced. These 150 bhp, petrol injected 6-cyl., RHD cars were not exported in any significant numbers. Approx. 800 thought remain in England. Only about 9 or 10 believed in the US.
TR250, 1967-68: 8480 of this LHD, carbureted model produced for the US market. 600 thought to survive.
TR6, 1969-76: 77,938 US/carb and 13,912 P.I. UK units produced. It's thought 6500 carbureted examples survive in the US, while about 4500 P.I. cars might be found elsewhere in the world.
TR7, 1975-81: 112,368 produced, 88,000 of which were exported. 3500-4000 worldwide, of which approx. 1000 are in the U.S., while "the majority" are in the UK.
TR8 (he doesn't state production years or export figures, and I'm too lazy to go look it up elsewhere): 2095 produced, 1250 of which thought to remain worldwide, but only 50 to 75 thought to be in the UK.
Since he's writing about the TR line specifically, no numbers for Spits, GT6 or various other Triumphs are cited.
Hope this partial answer helps!
