My 1958 TR3A reads 78023 on the speedometer but it's been around once so it really is about 178023 miles. I write "about" because when I bought this TR brand new in May, 1958, it came with a 3 month, 3000 miles guarantee. I drove almost that far in the first month, so I reached up under the dashboard and disconnected the drive cable so it wouldn't go over 2900 miles on the clock. When I took it back for the 3-month check-up, I re-connected the cable before I arrived at the dealer's shop. Also I rallied my TR quite a bit in its first life from 1959 to 1964 and connected the speedo drive cable to a Halda Speedpilot. I also remember that I drove the car for about a year with a broken cable where the mileage didn't move. I could guess the MPH by watching the tachometer. So I'd guess I must have about 10,000 miles more than what the speedo reads.
I do know for sure that since I finished the restoration in 1990, I have driven it 97,688 miles. The photo was taken at VTR 2007.
