The car tune up cost can vary based on how much is needed in the tune up, type of car, as well as if any new parts are needed. A car tune up can be as low as $50 dollars, but it can actually be several hundreds of dollars in the end. You must factor in that a tune up may require not only parts, but also a lot of labor hours, which is not cheap. Labor rates can range from $40 to as much as $150 depending on where you choose to get your car tuned up. You may want to shop around to see if there are any specials on car tune ups. Usually you can find small auto shops that offer a nice one time deal to get you into their place, and hope that you continue to use their shop in the future. A car tune up includes the checking and possible replacement of parts like the spark plugs, air filters, pipes & belts. It also may include simple maintenance tasks such as tire pressure check, tire rotation, an oil change, and other fluid checks (brake, coolant, etc.). One of the most expensive tasks is having your transmission fluid flushed. You should have that changed every couple years and can run you around $200. Overall, a car tune up is usually done every few years at around 50,000 miles. It may cost you a lot, but it can increase the life span of your car by years if you fix and replace any bad parts.
