What to Do After Buying a Used Car

By Viola Travers · Practical Services & Civic Guide

The first week: paperwork and inspection

After you buy a used car, your first task is to transfer the title into your name. You have a limited window to do this—South Carolina gives you 30 days. Go to your county's Department of Motor Vehicles office with the signed title from the seller, your bill of sale, proof of insurance, and a photo ID. The DMV will issue you a new title and registration in your name. Do not delay this step. Driving without a title in your name can create legal problems if the car is in an accident or gets towed.

Before you drive the car much, take it to a mechanic you trust—not the dealer, and not a shop the seller recommends. Pay for a pre-purchase inspection if you did not have one before buying. A mechanic will check the engine, transmission, brakes, suspension, and fluid levels. They will also run a diagnostic scan to catch any hidden problems the seller may not have disclosed. This inspection costs between $100 and $200 but can save you thousands if the car has serious issues you did not know about.

Key Takeaways

  • Transfer the title to your name within 30 days at your county DMV with the signed title, bill of sale, proof of insurance, and photo ID.
  • Have an independent mechanic inspect the car within the first week to catch problems the seller did not disclose.
  • Update your insurance policy to cover the specific vehicle and confirm coverage begins before you drive it off the lot.
  • Check the vehicle history report for accidents, flood damage, or title problems that may affect the car's value or safety.
  • Set up a maintenance schedule based on the car's age and mileage, and keep all receipts for repairs and service.

Insurance: what you need before driving

You must have insurance before you drive the car off the lot. If you already have a policy with another vehicle, call your insurance company and add this car to it. Tell them the vehicle identification number (VIN), the year, make, model, and mileage. Your agent will quote you a rate based on the car's age and condition. The policy should start the same day you buy the car, not the day after.

If you do not have existing insurance, you will need to buy a new policy. You can get quotes online from major insurers or work with an independent agent who can shop multiple companies. For a used car, most lenders require liability coverage (which pays for damage you cause to others) and collision and comprehensive coverage (which covers damage to your own car). If you own the car outright with no loan, you can choose liability only, but that leaves you paying out of pocket if your car is damaged or stolen.

The vehicle history report and title check

Before or right after buying, order a vehicle history report from Carfax or AutoCheck using the VIN. This report shows whether the car was in accidents, had flood damage, was declared a total loss by an insurance company, or had the odometer rolled back. It also lists previous owners and service records if they were reported to the service network. A clean report does not may provide the car is perfect, but a report with red flags means you need to know what you are dealing with.

Check the title status at the same time. A clean title means the car has no liens (no bank or lender owns it). A salvage title means an insurance company declared it a total loss at some point, usually after an accident or flood. A salvage title car is legal to own and drive, but it is harder to insure and worth much less. If the seller did not tell you the title status before you bought, you may have grounds to dispute the sale, depending on the dealer's return policy.

Registration and emissions testing

Once you have the new title, you need to register the car with the DMV. Registration is separate from the title transfer. You will pay a registration fee based on the car's age and weight. In South Carolina, you can register online through the DMV website, by mail, or in person. You will need the new title, proof of insurance, and a photo ID. Registration is valid for one or two years depending on what you choose.

South Carolina requires emissions testing for most vehicles. You can take the car to any state-certified emissions testing station. The test checks whether your car's exhaust meets state standards. If it fails, you will need repairs before you can register it. Some used cars come with a short grace period for emissions testing—ask the dealer or check your paperwork. The test itself costs around $20 to $30.

Maintenance records and future service

Ask the seller for all maintenance records from the time they owned the car. These records show what has been serviced, when, and by whom. They also help you understand what the car still needs. If the seller has no records, ask them what they remember about major work—new brakes, transmission service, timing belt replacement. Write down the car's current mileage and the date you bought it so you can track when the next service is due.

Create a maintenance schedule based on the car's age and mileage. Most cars need an oil change every 3,000 to 7,500 miles, depending on the engine and oil type. Tire rotation, air filter replacement, and fluid checks should happen annually or every 10,000 to 15,000 miles. Larger services like transmission fluid, coolant, and brake fluid changes happen less often but are critical. Keep all receipts and records in a folder or digital file. These records protect your warranty (if the car still has one) and prove you maintained the car if you sell it later.

Warranty coverage and what it means

Most used cars come with no warranty, or only a short one from the dealer. Some dealers offer a 30-day or 90-day powertrain warranty that covers the engine, transmission, and drivetrain. Read the warranty paperwork carefully. It will tell you what parts are covered, how long the coverage lasts, and what you have to do to keep it valid (usually regular maintenance). If something breaks during the warranty period, contact the dealer or the warranty company immediately with the receipt for the repair.

If the car came with a manufacturer's warranty from when it was new, check how much time and mileage remain. Some warranties transfer to the second owner; others do not. Call the manufacturer's customer service line with the VIN to find out. A remaining warranty is valuable and can save you thousands on major repairs. Keep all warranty documents in a safe place and bring them with you if you take the car to a repair shop.

Updating your address and documents

Once the title and registration are in your name, update your address with the DMV if you have moved recently. You can do this online, by mail, or in person. Update your insurance company's records as well so your policy reflects your current address. If you financed the car with a loan, the lender will have a lien on the title. Make sure the lender's name appears correctly on the title document. If there is an error, contact the DMV to correct it.

Keep the title, registration, and insurance card in your car at all times. South Carolina law requires you to carry proof of insurance and your registration. If you are pulled over and cannot show these documents, you can be cited. Store a copy of the title at home in a safe place, separate from the original. If the car is stolen or totaled, you will need the title to file a claim with your insurance company.

Frequently Asked Questions

How long do I have to transfer the title to my name?

South Carolina gives you 30 days from the date of purchase. After 30 days, you may face penalties or fines. Go to your county DMV office with the signed title from the seller, your bill of sale, proof of insurance, and a photo ID to complete the transfer.

What if the seller did not give me the title?

Do not take the car home. The seller must sign the title over to you before the sale is complete. If they claim the title is lost or at a lender's office, they can request a duplicate from the DMV, but this takes time. Do not buy the car until you have the signed title in hand.

Can I drive the car before the title is transferred?

You can drive it home from the dealer or seller's location if you have insurance and a bill of sale. However, you should not drive it regularly or take it on long trips until the title is in your name and the car is registered. Driving without a current registration can result in a citation.

What should I do if the mechanic finds serious problems?

If the inspection reveals major issues like engine or transmission problems, contact the dealer or seller immediately. Depending on your purchase agreement, you may be able to return the car, negotiate a refund, or ask the seller to pay for repairs. If you already signed a bill of sale with "as-is" language, your options may be limited, so act quickly.

Do I need to get the car detailed or cleaned?

A professional detail is not required, but it can help you spot problems you might miss on a dirty car. Wash and vacuum the interior yourself to check for stains, odors, or damage to the seats. A clean car is also easier to inspect during maintenance visits.
