Drivers love Buick vehicles for the luxurious appointments, high-tech features, and enjoyable engines. You'll never have to miss out on all the technology features you want when you choose a Buick vehicle like the Envision, Enclave or Regal Tourx or Sportback. The Buick Encore is a fan favorite thanks to its high-quality cabin, user-friendly infotainment, and nimble handling thanks to the compact size. If there's one thing to love about your new Buick car or SUV, it's the long list of standard features you get with each. You'll see how easy it is to get the luxury vehicle you want, without having to spend your hard-earned savings in Greenfield WI. Proudly serving drivers from Wauwatosa, Monomonee Falls, Waukesha, West Bend, and the greater Milwaukee area.


Buying used doesn't have to leave you feeling like you're not getting the high-quality vehicle you want, while still keeping the price affordable. Buick and GMC vehicles are built to last, so you can be sure that if you buy a pre-owned car, truck, or SUV from us, you're getting the right blend of affordability and quality in Milwaukee. Sometimes buying a brand-new car, truck, or SUV just isn't in your budget. Buying a used Buick or GMC vehicle offers a unique opportunity for you. You can buy a like-new car, truck, or SUV that's packed with features, without having to spend all of your savings just to get it. That's what makes buying a pre-owned Buick, GMC, or any other pre-owned vehicle we have in stock such a smart financial decision.

If you're wondering what a Certified Pre-Owned car, truck, or SUV is, you're not alone. They're not like traditional used vehicles. Certified Pre-Owned Buick and GMC vehicles have to pass a strict multi-point inspection, be reconditioned, be less within 6 model years, have fewer than 75,000 miles, and have a clean title. You'll also get an exclusive 6-year, 100,000-mile powertrain limited warranty, a 12-month/12,000-mile bumper-to-bumper limited warranty, and most excitingly a $0 deductible! What Certified Pre-Owned Buick and GMC vehicles offer that traditional used ones do not is an undeniable peace of mind. You won't get this kind of security when you shop with a private seller or even at other dealerships. You'll be able to get the like-new car, truck, or SUV you need, for used car prices.


When it comes to service in the Brookfield area, you can't match the quality and attention to detail that our service technicians provide. We use only the best genuine OEM parts when servicing your Buick or GMC vehicle. This means you'll have peace of mind, every time you use our Service Center, knowing you're getting only the best parts, that are made to fit your vehicle. Skipping your routine maintenance like oil changes, tire rotations, and everything in between can save you money in the short term, but will end up costing you in major repairs down the line. We can handle just about anything, so give our service technicians a call and we'll get you back on the roads of Wauwatosa and beyond quickly.

If you're more of a do-it-yourselfer, our parts department can help you find the right part or accessory for your life in Brookfield. No matter if you're looking for tires, batteries, wiper blades, or even accessories like rubber floor mats, cargo boxes, or anything else, we can help you find the perfect one to fit your Buick and GMC car, truck, or SUV.


We know that financing can be a stressful process. Our financing team is here for you, through the whole process, so you will feel confident, happy, and sure of your loan or lease agreement. It doesn't matter if this is your first time buying a new car, truck, or SUV or you've been around the block a few times, our team is here to make the process quick and painless. Deciding between financing or leasing can be a tricky choice, but when you look at a few key differences, the choice gets easier. Leasing offers a typically lower monthly payment, with a smaller down payment requirement, but you also have to be wary of mileage restrictions, excess wear and tear fees and more. Financing is a favorite option of many who want to build equity, invest in a car they can have for years, but has a higher initial monthly payment.

When you're ready to get the ball rolling on your new, used, service, or parts needs in the Brookfield area, give us a call! We can set you up with a test drive of any of our models we have in stock, so you can easily find the perfect fit for you and your family quickly. Save time at the dealership when you take advantage of all our website has to offer. You can easily apply online for financing, schedule service appointments, and so much more.
