If I found or was given about 10k, my life would take a pretty nice turn towards being able to stop relying on my parents when a crisis happens.
My wife's car has a blown headgasket, and we were quoted by 2 mechanics that it'd be about 5k to fix since the engine overheated for a long period of time (sensors didn't tell us it was overheating) and needs to be replaced. This is dumb since I still owe about 5k on the car it's self so I'd probably just pay the car off to get out from under it and use the other 5k to find a better more reliable vehicle. Man, that shit would be nice.
