The Sedan market is dwindling as CUV/SUV sales surge past them. Look at Internet places like cars.com, autotrader, TrueDelta, and cargurus for the best deals like $6,000-15,000 off various models. Then have it shipped to your door, piece of cake.
For the best riding, performance, and fuel economy, look to Buick or Cadillac. They also have the most discounted price that usually competes against a segment down just on price alone.
I'm right behind you in age have owned or currently owned most of these cars.
