Classic 1984 Cadillac Seville

Classic 1984 Cadillac Seville. Was garaged and unused for many years, then brought back to full service about 5 years ago. In excellent condition, used as a regular in-town driver. Good tires (two new). A/C system recently worked on and blowing cold.
Smooth, comfortable ride. With a 250-cubic-inch engine, it's anything but a muscle car, but it does get decent mileage for a big luxury automobile. It's front-wheel drive, throttle-body fuel-injected. Automatic leveling. All power accessories work (windows, door locks) except for antenna. (I have a replacement that will go with the car, but you have to take off the right-front fender to install it.) Modern sound system with CD and USB inputs.
What doesn't work: It has some kind of vacuum issue that arises after more than a few minutes of highway-speed driving (and never during regular in-town driving). Affects transmission shift points, but goes away after a few minutes of slower driving. I think it's associated with an environmental system. Don't know about cruise control; have never used it. The odometer quit turning about 5K miles ago (around 87,000). And the aforementioned antenna.
Otherwise, it's in gorgeous shape and a very classy ride.
