People tend to be more friendly when you dress nicely. However if you are not in an expensive social environment, a craving for designer labels can make you look vain and the money spent goes to waste.
Cheap Used Cars
Cheap used cars like those you can find in a private shop or on craigslist, and/or those sold AS IS, can potentially cost you a lot of money. Unless you are familiar with the mechanics and have good idea about potential problems and cost of repair, a cheap used car can be a black hole for money. A trip to a repair shop can easily run up to a thousand dollar, not to mention the time wasted and anxiety it causes, e.g., a breakdown in the middle of the night or nowhere.
