Frustration

You can think of it two different ways
1. You throw money, time, effort towards the car because you like doing the work yourself, someone important gave it to you, it's just a fun hobby.
2. If you look at it from a economic stand point, don't buy project car. Just buy a restored one because 9 times out of 10 you'll come out ahead. Plus, by buying the car restored already you can enjoy it anytime you want instead of waiting till the project car is finished.
