Used to buy a Riviera every couple years up until '85, that's arguably the last well styled Buick. It shared some chassis pieces with Olds and Cadillac, and it had an Olds engine, wasn't a bad car at the time. The front drive Riviera's were great in the snow. Also bought a Skyhawk T Type that year, just a fancier Cavalier but not totally rebadged. Those were the last Buicks we ever bought.
Saw the Buick Avista concept a few years ago, if GM built that, it would get me back into a new GM vehicle again.
