I used to spend a lot of time on a site devoted to Ford Crown Vics, Mercury Grand Marquis, and Lincoln Town Car. A lot of these cars were "geezerized" either by dealers or by the original owners. The nasty tops can be removed, though not without considerable effort to achieve the desired result of making it look as though the car were always a slicktop. Oversized/gaudy wheels are easy to get rid of.
