A Ford 500 isn't a Panther, it's a FWD (or optional AWD) unibody platform. Crown Vics, MGM/Marauders, and Town Cars were the only Panthers. They are pretty good cars, and among the last of the old-school USA RWD big iron. For a V8 RWD, ~25 MPG is pretty tough to beat, and they are pretty durable. Otherwise, why would the PDs STILL be using them as cruisers to this day? Last fleet ones were made in 2011, so the newest ones are 12-13 years old now.I'd never buy a "new" new vehicle. If you are looking for ride, comfort, durability, pretty decent fuel mileage, and something that will go 400,000 miles with proper maintenance, look for a Ford product built on the Panther platform; Lincoln Town Car, Mercury Marquis, or Ford 500. I've owned a lot of different cars during the last 63 years, the last 5 of which have been Lincoln Town Cars. They've just been the best of the best~!
