15. Mercury Grand Marquis (Late Models)
The Mercury Grand Marquis, especially in its later years, embodies old-fashioned styling and a traditional, no-frills approach. Its boxy silhouette and lack of modern amenities don’t attract younger drivers or car thieves seeking valuable parts. With the discontinuation of Mercury and dwindling demand for Grand Marquis components, it’s rarely targeted for theft. As U.S. News highlights, the Grand Marquis’s outdated look and minimal market interest keep it safely off most criminals’ radars.
