The frustration level is very high, I've got a lot of money tied up in this car, a lot of time, and I've not driven it one block. Going on five years, I'm not wealthy.
Mine was in the bodyshop for two winters while I kept bringing $1000 dollar bills, as I was able. Then chassis for the third winter, finally the engine.
I ain't wealthy either, but I suspect my frustration tolerance might be higher. Or was, at that time,lol. That was 20 years ago, and the body is now returning to it's former pitiful state.
