The Buick brand revived itself by updating its simple luxuries for the 21st century, and the LaCrosse has been its poster child. It's tricked out with features such as touchscreen and voice-controlled navigation, audio and Bluetooth, heads-up instrument displays on the windshield, stability control, rearview camera, parking assist and rear-seat DVD players for the kids and grandkids. It turns out Americans who like Buicks love that stuff, as LaCrosse sales have climbed from just 28,000 in 2009 to nearly 69,500 last year after a huge tech overhaul in 2010.
