For families who like to travel together, we suggest investing in an SUV. Both Buick and GMC, realizing that today's ideal people-haulers come from SUV molds, have manufactured some of the country's most acclaimed crossovers. Buick's premier SUVs include the three E's: Enclave, Encore, and Envision. GMC also offers an incredible selection of SUVs, including the Acadia, Acadia Limited, Terrain, Yukon, and Yukon XL. Depending on your day-to-day and frequency of family getaways, each of these Buick and GMC models will get the job done, and then some.

Hard workers everywhere understand the importance of having an equally hard-working truck to back them up. The GMC Canyon and Sierra 1500/2500/3500 lineup of pickups are those workers' answers. If you're tackling a construction project in Los Angeles or need to move to Garden Grove or Santa Anita, be sure to get acquainted with our rugged GMC pickup trucks-they're bound to leave a lasting impression.

Our comprehensive selection of top-notch new Buick and GMC models doesn't end with SUVs and trucks. We also proudly sell and lease several Buick sedans, including the Buick LaCrosse, Regal, and Verano. These cars are the perfect vessels to explore Los Angeles at night, take you to Orange County for a day at the beach, and anything in between.
