The 2016 Buick LaCrosse is a large luxury sedan available in six trim levels: 1SV, Base, Leather, Premium 1, Premium 2 and Premium 3. The 1SV LaCrosse comes standard with the V6 engine, remote ignition, 17-inch alloy wheels, heated mirrors, dual-zone automatic climate control, an auto-dimming rearview mirror, an eight-way power driver seat (with four-way power lumbar), split-folding rear seatbacks, a tilt-and-telescoping steering wheel, cruise control, OnStar telematics with 4G LTE connectivity and WiFi capability, Bluetooth phone and audio connectivity, the IntelliLink infotainment system (with an 8-inch touchscreen display and smartphone app integration), a rearview camera and a seven-speaker sound system with a CD player, satellite radio and two USB ports. If you want any other equipment, we advise you to move up to the Base trim level at least, as the 1SV isn't eligible for most options. At the Base trim level you get all the 1SV's equipment plus 18-inch wheels and a cargo net. The available Sport Touring package adds unique 18-inch wheels, a rear spoiler, the Comfort and Convenience package #2 (rear parking sensors, auto-dimming side mirrors with integrated signal repeaters, ambient lighting, keyless entry and ignition, and driver memory settings) and the Leather package (leather upholstery, heated front seats and an eight-way power front passenger seat). Spring for the Leather model and you'll lose the Sport Touring package's wheels and spoiler, but you get the Comfort and Convenience package #2 and the Leather package as standard. LaCrosse Leather V6 models get 18-inch wheels of their own (19s with AWD), while four-cylinder models roll on 17-inchers. Standard safety features on the LaCrosse include antilock disc brakes, stability and traction control, front and rear side-impact airbags and side curtain airbags.
