I did the same, I failed to buy the car that was my childhood dream, BMW E30 M3, red color. I could have done it when I bought my first car, but then I had to buy something less powerful, later I bought cars of a newer generation, and now if I could afford another car, it couldn't possibly be such an expensive restored car... so, it remains a childhood dream 😀
Childhood dreams are good to have I think, as are adult goals.
