I think you are making my point actually, Ian. Its not about luck, its that these cars were not designed for quarter mile traps on real tracks. As mentioned before, they were not designed for being stop light warriors. If you work a machine in a way that is was not designed for, more often than not you will get premature failure. If you use it as it was designed, and do proper upkeep, you mainly will not. But that aside, 220k is a very good number to needing initial transmission work. Its a big pile of moving parts and eventually it will always need rebuilding. If you got to that high first, you did just great and I do not think you have anything to complain about. Particularly if you were using it hard at the track and the stop lights.
