Explore New Buick and GMC Lease Specials and Deals Near St. Charles County, MO

General Motors releases updated incentive programs each month, and the deals available on new Buick and GMC vehicles can vary based on the model, trim level, and the time of year. Understanding the types of programs available helps you identify which offers apply to your situation before you visit. Here's a breakdown of what we typically see available:

• GM Manufacturer Incentives — These are cash allowances and bonus offers funded directly by General Motors. They're released on a monthly cycle and often vary by model and trim. Some months feature deeper incentives on outgoing model-year vehicles; other months offer stronger deals on freshly launched models.
• Lease Programs — GM Financial regularly makes lease programs available on select Buick and GMC models. Lease deals typically feature defined money factors and residual values that change month to month, making certain models more attractive at different times of year.
• Purchase Allowances and Loyalty Offers — Current GM vehicle owners may qualify for loyalty bonuses that can be applied toward the purchase or lease of a new Buick or GMC. These are designed to reward customers who are already in the GM family.
• Conquest Offers — If you're currently driving a non-GM vehicle, GM frequently makes conquest incentives available specifically for customers switching brands. These can represent meaningful savings when combined with other offers.
• Seasonal and Event Promotions — GMC's annual Truck Month, year-end events, and holiday sales are some of the most popular promotional periods. During these windows, the combination of manufacturer incentives and dealership programs can produce some of the most compelling deals of the year.

We keep our new vehicle specials page and our manager specials page updated regularly so you can always see what's currently available before you visit or reach out.

Our Buick lineup offers something for every buyer — from the compact and stylish Envista all the way up to the spacious, three-row Enclave. Each model has its own incentive profile each month, and several are frequently featured in GM's active lease and purchase programs. We also carry award-winning Buick vehicles recognized for quality, reliability, and customer satisfaction. Here's a look at what makes each model a strong value choice:

GMC is one of the most incentive-rich brands in the GM portfolio, and the brand's annual Truck Month promotion — typically held each fall — is one of the best opportunities all year to get into a new Sierra, Canyon, or other GMC model with manufacturer support behind the deal. We carry the full GMC lineup at our St. Peters dealership, and our team stays up to date on every active incentive program so we can match you with the best available offer for your specific model and situation.

The GM Rewards program is one of the most underutilized advantages available to Buick and GMC owners — and it's free to join. Every time you purchase an eligible GM vehicle or visit a GM dealership for service, you earn points. Those points can then be redeemed toward the purchase or lease of your next new Buick or GMC, effectively giving loyal GM customers an additional layer of savings on top of whatever manufacturer incentives are already available.

Here's how the program works in the context of shopping for a new vehicle with us:

• Earning Points — Points accumulate on new GM vehicle purchases, qualifying service visits, and purchases through affiliated GM Rewards partners. The more you stay within the GM ecosystem, the faster your balance grows.
• Redeeming Points at Purchase — When you're ready to buy or lease your next vehicle, accumulated GM Rewards points can be applied directly to the transaction — reducing your out-of-pocket cost in a meaningful way.
• Loyalty Bonuses — Beyond the standard points program, current GM owners may qualify for additional loyalty incentives when transitioning to a new Buick or GMC. These offers are available on top of other active GM incentives and can stack to create significant overall savings.
• Conquest Offers for New GM Customers — If you're currently driving a vehicle from another brand, you may qualify for a conquest offer that makes switching to Buick or GMC even more financially attractive. Ask our team whether an active conquest program applies to your situation.

The Suntrup Lifetime Powertrain Loyalty Program

Every new vehicle purchased from us comes with something no manufacturer incentive can replicate: the Suntrup Lifetime Powertrain Loyalty Program. When you buy new here, you automatically receive two full years of complimentary maintenance through our 5 Works Packages — covering synthetic blend oil changes, tire rotations, and multi-point inspections — at no additional charge.

Beyond the complimentary maintenance, every new vehicle purchase includes lifetime powertrain protection for as long as you own the vehicle. This covers the engine, transmission, and drivetrain components — and it's our way of standing behind every new Buick and GMC we sell with a commitment that extends well past the manufacturer's factory warranty.

Combined with our no-dealer-fee pricing and the GM incentives available this month, the Suntrup Lifetime Powertrain Loyalty Program makes buying new from us one of the strongest overall value propositions in the St. Charles County market.
