well the cost of happiness is hard to put into perspective... my house makes me happy and it is very pricey (at least to a 24 yr old right out of college), my cobra has the most money wrapped up and makes me very happy during the summer, the lincoln has been a fairly cheap car to own and makes me happy to have a great running mildly fast summer dd, my f250 has some money wrapped into it but without it i couldnt pull some of the things that i do to make me happy (like pulling the chevy home) and my chevy, which is by far my cheapest vehicle right now makes me happy because it doesnt have very much of my money wrapped up, its in good shape, has all the body parts on it now, has good rubber, runs like a champ, and i only have $1075 in it including the cost of the truck. I dont do it cause I care how much money is in them, I do it so I can see which one is costing me the most relatively to each other. Now with that said I am inheriting a 77 GMC 3/4 ton camper special that needs completely restored and I know i will probably have about $8k in it when its all said and done but its a truck that my fiance's grandfather ordered and i would be happy to keep it in the family.
