Buying a used car in Illinois can sound like a daunting task, but the complexity, which might scare you, is in place to protect buyers from predatory sellers. Proper titling ensures that you aren’t buying a stolen car, or later being accused of stealing the car you rightfully bought.

Illinois also doesn’t want you buying a hunk of junk that can only make it off the lot before failing on you. With that in mind, let’s go over the process of buying a used car in Illinois from a dealership or a private seller.

Buying a Used Car From a Dealership

Before stepping onto a used car lot, there are a few steps you need to take. First, you need to figure out which car you want, and how much you should be paying for it. CoPilot can help with this step, letting you utilize the same software as the dealerships to see inventory near you, and provide you with an estimate of the real value of that vehicle in addition to the listed price. Remember, you can negotiate for a lower price if the dealership is asking too much, and you can always walk away if they won’t give you the deal you want. 

Once you know what car you want to buy and how much you intend to spend on it, you should find a trustworthy lender with interest rates and policies that work for you. Unless you can afford to buy the car outright, you will need financing. A dealership will likely offer to either finance the car themself, or connect you to a local lender during the purchase process. While these financing options may be just as good, or even better, it is always best to secure financing you know you can afford before getting attached to a car and feeling cornered into just one option. 

You should set up a pre-purchase inspection from an unaffiliated mechanic you trust. Some dealerships will allow you to take the car off the lot to bring it to an inspection site, but if not you will have to find a service that will travel out to the dealership. Even certified pre-owned vehicles that have passed a manufacturer’s or dealership’s inspection should still get inspected by a professional. A private inspection may reveal issues that are fine now but could deteriorate over time and lead to expensive repairs down the road.

One benefit of buying a used car from a dealership is that they will likely provide you with a vehicle and title history report. This will let you know if the car has been in any fender benders or has been totaled, or anywhere in between. It also lets you know if the car has ever been stolen or used as a police vehicle.

You should understand your warranty coverages. Depending on how old the car is, it might still be under the original manufacturer’s warranty. The dealership may also choose to sell a car with their own warranty program. But any used car from an Illinois dealership with under 150,000 miles on the odometer that hasn’t been rebuilt or recovered from a flood must come with a 15-day/500-mile powertrain warranty.

If the powertrain fails within that period, the dealership must take the car back and return your money to you if they can’t repair it. But be careful, this warranty can be voided by off-road usage, towing, racing, or any extra strenuous driving. If this seems unfamiliar from the last time you bought a car, that’s likely because the law was passed in 2018 to make buying a used car in Illinois safer for the consumer.

Once you have found the car you want, agreed to a price with the dealership, and agreed to buy it, your responsibilities should be done. Most dealerships will file the necessary paperwork to transfer the title to you and get the vehicle registered with the Illinois Secretary of State, and get all work out the sales tax. The dealership can charge you for these services, but, under Illinois law, that charge cannot exceed $300.

Once you have gone through that process, congratulations on your new car! The dealership has 20 days to submit your car’s sales tax and transfer of title to the Secretary of State’s Office.

Buying a Used Car From a Private Seller

Luckily, much of the process is the same between buying a used car in Illinois from a dealership or a private seller. You still want to do your own research to make sure that the listing is being sold at a reasonable price depending on its model, age, mileage, condition, etc. You should also secure the best financing option possible beforehand (unless you plan to buy in cash), as a private seller is not going to offer you financing options on their own. And you should also get the car inspected by a mechanic. It’s especially important since private sellers don’t have to offer the same protections that dealerships do. But from here on, there are a few differences in the car buying process.

Once you are in contact with the seller,you will want to ask for the VIN number. This will allow you to search for the vehicle’s title history report on your own, through the National Motor Vehicle Title Information System, CarFax, or any other similar service.


IS GAP INSURANCE WORTH IT?

Gap insurance can prevent you from making payments on an already-totalled car, but is gap insurance worth it? We break down what gap insurance is, if it’s worth it, and more - simply and with plenty of examples. 


This is extra important since the Illinois Secretary of State’s Office will not issue a title or transfer a title for any car that has been deemed a total loss, or junk. It is important that you know this before you buy the car, as a private seller might not know about this, especially if they recently moved from out-of-state, and may unintentionally sell you a car that you can’t legally drive. 

You also need to see the car’s title before buying it. Any alterations made to a title document will invalidate it, so on top of making sure that the VIN and the seller’s name match the title exactly, you have to make sure the title hasn’t been tampered with.

Once you have bought the car, immediately take the old license plates off. Past that, it is up to you to get the title transferred to your name and get the sales tax paid to the Secretary of State within 20 days.
