The Buick Regal, the mainstay of the automaker’s fleet, sees some modest changes with year with the addition of the Avenir trim level. While the hardware is the same, the goodies appear inside the plush cabin. It has an eight-way power driver seat with lumbar support, leather upholstery, heated front seats, chrome accents, door mirror memory, a navigation system with voice activation, and front dual-zone air conditioning with automatic temperature control. The LaCrosse also gets a brand-new Sport Touring edition to add to its lineup. It dials it back a bit on the standard features and balances it with a performance upgrade under the hood and some style enhancements including new 19-inch wheels and a black grille. It adds to its list of available amenities with automatic emergency braking and massaging front seats. A backup camera with rear park assist, auto-locking doors, and two USB ports come with the base build.
