I have tried in the past to put some cash aside, but it seems to be consumed by life... I am the sole wage earner around here. I need to provide a roof over our head, food on the table and everything else that we need for our 2.5 girls.... I made a deal with my wife when we decided to have kids - I get a car for each, when we can afford it. So far, I am keeping pace. Girl #3 is due in July and I may have to wait a while for the next one, but it will come. Stuff comes up that I need on Craigslist all the time...sometimes the money is there, sometime it isn't. She has no interest in my hobby. She has only ridden in one of my cars....once. But she knows it is important to me and supports my hobby fully. She even supported me buying a storage condo to keep them in - so it is a pretty expensive hobby for me all in when you add up the cars, parts, tool and a mortgage. No money to really keep from her, no need to keep it from her if I did.
