Frequently Asked Questions


While we perform work by appointment only, you are always welcome to visit our shop during business hours. Bear in mind that if we are busy, we will be tending to customers who have come in on appointment first, but if we have time free, we will be glad to discuss your vehicle and your service needs. If your vehicle is not able to be driven safely, please contact us to arrange a tow-in so we can ensure your vehicle arrives safely.


Absolutely, we are always happy to provide an estimate of the work needed. For repairs and diagnostics, we will need to see your vehicle IN PERSON in order to provide you with the most accurate estimate. Estimates cannot be provided over the telephone. Once we see your vehicle, we will absolutely contact you and get your approval BEFORE any work in begun. Do not be misled by other shops estimating repairs or providing quotes over the phone. The vast majority of the time it simply isn’t possible to give an accurate repair estimate without seeing the vehicle and having it diagnosed by one of our trained technicians. We have had many vehicles with very high repair estimates arrive at our shop only to find it was something minor, or that the previous estimate was for something not even needed to address the issue. We have also seen minor estimates from other shops missing something major. You want an accurate assessment of your vehicle and MPC can provide you with that. Call us today to schedule your appointment at 312-432-9492.


We warranty all work that we perform for 3 years and 100,000 miles. If the part that we installed fails during that time or mileage period, we replace it and you pay nothing for parts or labor. All warranty work must be performed by Midwest Performance Cars.


We use Original Equipment Manufacturer (OEM) and Original Equipment Supplier (OES) parts, straight from the dealer network or professional parts suppliers. The ONLY exception to this would be a specialty part needed due to a special circumstance (out of production, unavailable, or customer-specified parts which meet our quality standards). WE WILL NOT INSTALL PARTS PROVIDED BY THE CUSTOMER.


We are able to perform your necessary regular, scheduled, and preventative maintenance for your vehicle. Your scheduled maintenance must be performed to maintain your warranty, but you are not required to go to the dealership for this service. Your receipt from us is proof of service in case of any manufacturer warranty claim.


Many vehicles are fitted with an engine timing belt that requires replacement between 60,000 and 100,000 miles. On many of these vehicles, a timing belt breakage can result in thousands of dollars in engine damage. If you have purchased your automobile used and do not have records of the timing belt being changed, we can inspect your vehicle and determine its condition, and if it is due for replacement.

Q: I want to make sure I’m covered under my car warranty, do I have to go to the dealer to be covered for maintenance?

Absolutely not. The Federal Trade Commission (FTC), the nation’s consumer protection agency, states that it is illegal for a dealer to deny your warranty coverage simply because you had routine maintenance or repairs performed by someone else. Routine maintenance often includes oil changes, tire rotations, belt replacement, fluid checks and flushes, new brake pads, and inspections. Vehicles owners and lessees are completely within their rights to use an independent repair facility for their vehicle’s maintenance and repair.

Q: How often do I really need to have my oil changed?

The general rule of thumb is for conventional oil (most frequently found in much older vehicles), you should change oil every 3000 miles, and for synthetic oil every 6000 miles. Best practice is to adhere to the maintenance schedule in your owners manual and change oil by the mileage or time interval specified, whichever comes first. Some manufacturers have begun to claim that oil life can be stretched to 10,000 miles, however, even if the oil has not broken down, become saturated with contaminants, or lost viscosity, without an oil change, you are still circulating through the same dirty oil filter. We have removed oil filters that had shriveled up like raisins after exceeding the oil change mileage interval. Oil life is also dependent upon driving conditions. If your vehicle is primarily used for short trips and rarely operates on the highway for extended periods where it can reach full operating temperature, it can become contaminated more quickly with moisture and unburned fuel. When compared with the cost of an engine repair due to poor lubrication, regular oil changes are an inexpensive maintenance necessity.

Q: How much should I be paying for oil changes?

Conventional oil changes can run from $40 to $80, and synthetic oil changes can run from $70 to as much as $250. How many quarts or liters is the engine oil capacity? What grade oil does the manufacturer specify? Does your vehicle require conventional or synthetic oil? These factors all go into determining price. When you see a sign or get a mailer advertising the “$9.99 oil change special”, there is usually fine print at the bottom which reads something like “Up to 5 quarts, conventional oil only. Additional oil or synthetics subject to additional charges”. So the oil change bargain usually will end up being at or near any shops regular oil change price. In our view, it is much more important to use a shop that you trust, who knows the brand of car you have, and that you know will be using the proper oil and parts for your vehicle. We have seen vehicles come into our shop for the first time, with incorrect oil filters, filters that clearly had not been changed in years, and wildly incorrect oil levels, all of which can result in major engine damage. Do your vehicle a favor and don’t skimp on oil service just to save a few dollars. It is a very important part of extending the life of your vehicle.

Q: How do I know if my vehicle needs to be maintained with synthetic oil changes?

You should always refer to your owner’s manual for the factory recommended oil type. The only exception to this rule is: Even if your car only requires conventional oil, but has been changed to synthetic, DO NOT change back to conventional. Once you’ve gone synthetic, you should stay with it for the life of that vehicle.

Q: Should I keep maintaining my car or buy a new one?

In general, it is more cost effective to properly maintain your existing vehicle than purchasing a new one. A new vehicle experiences immediate depreciation upon leaving the dealer lot, generally will cost more to insure, and will require roughly the same expenditure on all wear items such as brakes, tires and fluids (which are not covered under warranty), that your existing vehicle requires. For a real-life cost comparison, you can click over to our Youtube channel where we have posted 2 videos, “BMW cost comparison” and “Porsche cost comparison” on this exact question:

Q: How often should windshield wiper blades be replaced?

Blade manufacturers, some repair shops, and auto parts stores will tell you to replace your wiper blades every 6 months.

We advise to replace them if they are: chattering, streaking, smearing, squealing, or outright broken. If yours last a full year, great! It’s pretty easy to tell if your blades need replacing, you’ll see it (or not see anything) right in front of your face! Vehicles that live on the street, are exposed to the sun or other conditions daily, will not last as long as a garaged vehicle. Have your repair shop check your blades when you go in for an oil change.

Q: How much should a water pump cost?

Ahhh, here’s a “phone question” that we often get. “How much is a water pump?” Again, prices can vary wildly based on model of car and type of engine in your particular vehicle, as well as are you in the “rust belt” part of the country, or are you in a corrosion-free, sunny and warm climate. All of these factors go into the price of the part, and the amount of labor involved in replacing the water pump. In order to provide an accurate quote, we need to see your vehicle, but that does not cost you anything. At our shop, we will perform a 36-point inspection of your vehicle free of charge, and provide you with a digital inspection form detailing the condition of your vehicle. We would also provide you with a written estimate of the recommended services, which would include the water pump replacement if needed.
