I have a near pristine similar car, the Grand Marquis with dual exhausts etc. Not quite a Marauder but close. It is more like driving your living room but easily impresses the youngsters and gets 27 mpg. One of the best cars ever made. The B body from GM was in the same league.
In 1984 my father bought a Caprice Classic. It had a 350 V8 with a four barrel carb. Basically the same engine and transmission they used in cop cars. My that was quick.
In 1989 he traded that in for another Caprice although this one had a 305 and the 2 bbl.
