1. Why Buying Used Makes Sense in 2025
Buying a used vehicle is a smart bet for cost-conscious shoppers. While used car prices are higher than historic averages, they still offer significant savings compared to new models. Summer is the buying season, so staying on top of market trends as you plan your used vehicle purchase is important.
In March 2025, the average used car selling price was $25,182. This means buyers can still buy quality vehicles without breaking the bank for a brand-new car. At Thompson Sales, we bring over 100 years of experience to the table. We’re here to help as you consider used options that fit your budget and lifestyle.
2. Benefits of Buying a Used GMC or Buick
A used GMC or Buick means proven reliability and fantastic features–all at a lower price point. These brands are known for durability and strong resale value. GMC trucks and SUVs offer robust performance, while Buick is praised for smooth handling and comfort.
Buying used lets you enjoy luxury features and trims that might be out of reach on a new-car budget. Our selection of used Buick and GMCs includes a range of cars and SUVs. Stop by our dealership to find your next used vehicle.

3. Set the Budget for Your Used Vehicle Purchase
Before you start shopping for your next car at Thompson Sales, take a moment to figure out what you can afford. This step isn’t just about the sticker price. It’s about making sure your new ride fits in your budget for the long haul. Here’s what to consider:
Purchase Price
The monthly payment is important, but there’s more to it than that. Experts recommend that your car payment should be no more than 10-20% of your take-home pay. If you’re planning to finance, factor in your down payment, the loan term, and interest rate. A larger down payment can lower your monthly costs and the total interest you’ll have to pay over time.
Vehicle Taxes and Fees
Vehicle costs go beyond the dealership. When you buy a new car, you’ll need to pay sales tax, registration fees, and property taxes. These are usually due when you purchase the vehicle, so be sure to include them in your budget calculations.
Car Insurance
Insurance premiums can vary widely based on the car’s make, model, your driving history, and even your ZIP code. It’s smart to get insurance quotes before you buy, so you’re not caught off guard by a higher-than-expected bill.
Maintenance, Repair, and Fuel Costs
Whether new or used, every car comes with ongoing expenses like oil changes, tire replacements, and repairs. Some vehicles are more affordable to maintain than others, so look into the specific costs for those models.
Depending on your driving habits, gas can be a major part of your monthly car budget. Choosing a fuel-efficient car can save a ton at the pumps. Or, you can choose an electric vehicle and skip the gas station altogether. However, you’ll need to plan for EV charging stations near you and along vacation trips.
Car Payment Calculators and Price Guides
Use online tools and price guides to see what models fit your budget based on year and mileage. When you buy a used Buick or GMC at Thompson, you can use our payment calculator to break down the details. Setting a clear budget helps you focus on vehicles that meet your needs without stretching your finances.
4. Certified Pre-Owned vs. Regular Used Vehicles
While shopping, you’ll see or hear the term “certified pre-owned.” But what, exactly, does that mean? Let’s take a look at the differences between a certified pre-owned vehicle and a used vehicle.
A certified pre-owned vehicle has low mileage, is in perfect condition, and has a clean vehicle history. Usually, they’re less than seven years old.
These vehicles offer more peace of mind than a standard used vehicle. They undergo thorough inspections, come with extended bumper-to-bumper warranties, and include added perks. Regularly used vehicles may cost less upfront, but they don’t always include these benefits. If you want security and quality, a certified pre-owned GMC or Buick may be the right choice for you.

6. How to Evaluate a Used Vehicle Before Buying
When buying a used vehicle, understanding what you’re (literally) getting into is vital. Here’s how to make sure the car is in top condition before you drive it off the lot.
- Review the vehicle history report for accidents, title issues, and previous ownership.
- Inspect the car in person for signs of wear, tear, rust, or body damage.
