1966 Mercury S-55

This 1966 Mercury S-55 is beautiful unrestored car that still has its original paint and interior. It’s also well equipped with nearly every factory. option available at the time. It was originally delivered to District Sales Office (DSO) 84 which translates to “Home Office Reserve” which was generally used for “Employee Use” which perhaps goes some way to explaining all the options.

After a two year hiatus the sporty S-55 returned in 1966 for one last two-year run. It replaced the 1965 Park Lane Sports Package option.

The S-55 was only available in two variants; a two-door hardtop and the convertible you see here.

Inside, the bucket seat interior is original – all-vinyl was standard on the convertible. Its condition would appear to reflect the 40,000 miles that is showing on the odometer.
