Step 1 – Take your car to several repair shops for inspection.
Let's say your car makes a thud and metallic sound every time you press the brakes, then you take your car to the local repair shop that you spent a day and a day on the way to work . The first thing you should do is to let the editorial department know that you are here for an inspection and not to perform any services until you have the chance to authorize them. Ask them to inspect your vehicle and offer you a price. If the service technician comes back to you after the mechanic has performed the inspection and says that your car needs additional repairs, this could be a red flag. Keep in mind that when an editor comes back with additional repairs, he does not necessarily refund the bill. What you need to pay attention to is how he or she explains the extra repairs. If the service writer goes into great detail about the need for extra repairs just leaving you to forget why you bought your car for inspection in the first place, be weary. Take your car to another auto repair shop or mechanic for inspection. See if they come back with the same result. I would do this until you feel comfortable with the repair shop and / or the mechanic.
Step 2 – Do not let the repair shop or mechanic put your car on the rack and start disassembling it until you give it permission.
If you do not do this, you may be forced to allow unnecessary and expensive repairs just to take your car out of the rack. You may have to pay a large fee to reassemble your vehicle. This is not a good situation and you unfortunately want to avoid it.
Step 3 – See how the maintenance department explains the extra repairs.
When you bring your car for an oil change / inspection and the service editor hits you with a list of extra repairs. If he or she is talking about extra pairs and the importance of them only letting you forget why you bought your car for work in the first place, this could be a red flag. Not all mechanisms are bad and try to take advantage of you, but keep this situation in mind.
Step 4 – Ask the repairer and / or mechanic to detail your repairs.
Tell the writing department to include the price of the parts and the hours worked planned. If they fail to give you the detailed information, something could be in place. If they give you a detailed invoice, you now have the opportunity to do some research. Go home and try to find out as much as you can about the planned work, or better yet, bring your itemized bill to another repair shop and ask for a quick look.
Step 5 – If you are doing your service including tire rotation, try marking your tires (quietly, of course).
For example, mark the front tire on the driver's side with the number 1, then mark the rear tire on the driver's side with the number 2 and so on. Take a picture with your camera phone (assuming you have one) or a digital camera for documentation. When you take your car to the repair shop, before paying the bill see if the tires have been turned. If they are not turned, you have proof that something is wrong and you can rest assured that the repair shop is not going to try to bother you from that moment.
