How much do Car Repairs usually Cost? Here's the most important questions to ask before spending money repairing your vehicle.

Your Trusted Auto Repair ShopPrice shopping for a gallon of milk is relatively easy. There are a lot of regulations controlling food so the quality is somewhat uniform. Other grocery items may be a little more difficult – we have to read labels and calculate price per ounce because the packaging may be different sizes. When we move to things like clothing or appliances, we have to work a little harder to be educated consumers. The fact that some advertising is misleading makes the process even that more difficult.

In any type of service business, the challenge goes up exponentially. Parts like roof shingles, plumbing valves, and alternators vary in quality. Without expertise in those fields, it is almost impossible to really tell the difference. Labor is even more difficult. What unseen details are included or overlooked?

The absolute best way to compare is to interview others who have done business with the companies you are interested in. Once you have decided to check pricing, here are some questions you should ask.

  • Is the estimate just parts and labor?
  •  Does the estimate include tax?
  • Are there additional charges for shop supplies or waste disposal?
  • How long is the warranty?
  • Does the warranty cover parts and labor?
  •  Is the estimate padded a bit to cover any unknowns?
  •  Is there a guarantee that the estimate will not be exceeded?
  • Are tow bills or any additional failures covered due to a warranty issue?

The reality is that in most cases, no shop can give you an accurate estimate without first inspecting the vehicle. Ultimately, it’s best to choose a shop you are comfortable with – one that you are confident is giving you everything you pay for. A year after the repairs are completed you will remember the quality far more than you will remember the price. In the end, quality repair shops are going to be very similar in price.

Repair shopping can be very confusing. If you have any questions about a particular situation, please give us a call. Even if we are not in the running for your business, we’ll still be glad to give you information to help you make your best choice.

Importance of Routine Battery Check-Ups

As cars become more technologically advanced, the importance of your vehicle’s battery becomes continually more important. In the old days, a car battery essentially worked, or it didn’t; if it was good enough to start the car, it was good enough. Moderns vehicles are a different story. A faulty battery can cause a variety of issues, including engine codes, sensor failures, irregular transmission behavior, and the list goes on. Battery failure often causes issues that are commonly misdiagnosed, and in the hands of the wrong auto repair shop, a mechanic may spend hundreds of your hard-earned dollars chasing problems that don’t exist. At Mercie J Auto Care in Mesa, AZ, our mechanics are familiar with modern vehicles and the problems that accompany them.

Is it wear & tear or a serious problem?

It’s not always easy to recognize when your vehicle is suffering from a simple problem that requires a little maintenance and TLC or there is real engine damage as symptoms can be overlooked and seen as “normal.” While not all sounds and smells may threaten the life of your car or truck engine, there are some obvious warning signs that require a vehicle inspection here at the shop right away.
