If you don't already know how then check out a book from the library and car repair and start reading about the basics.. All fixing cars is is just screwing and unscrewing bolts, and knowing how it all fits back together. At no time should you ever need to take your car somewhere to replace say brake pads. that's one of the easiest things to fix on a car and also one of the most expensive to have done. If you have to go to a mechanic you should be learned about his trade and be able to speak his langauge -- show from the get go you know what you're talking about. Shady mechanics prey on ignorance.. it's not always a woman thing because some guys don't bother learning how to work on cars anymore and if they seem gullible they'll be taken to the cleaners too. But you should at least know how to perform rudimentary car repair. Just beware the cheapish tool sets at wally world and car parts stores.. they are designed to break thus bringing you back to them to buy replacements. Save a little more money and watch Sears for sales on Craftsman tool sets. If any craftsman tool breaks (no matter how long its been or how it was broken) Sears will replace the tool absolutely free, no questions asked.
