You're thinking about much newer Lincolns. These Town Cars were bigger, offered more interior and trunk room, and featured a ton more standard features and options. Not only that, but a 1980s Town Car looked far more commanding and elegant than the Crown Victoria/Grand Marquis. Today's cars are the ones that are rip offs of each other.
I donated my fathers estate white 1988 Town Car to Goodwill. Worth around 500. I drove it on a limited basis. Very wide and hard to park. Fuel usage was high. This was in 2007 when gas prices kept climbing. He had to replace all the fuel lines due to corrosion. It was all original except for the wide clear bug screen added on the front. Not a car for everybody.
