Drive The Coast in Santa Rosa Beach, Florida, is asking $55,000 and accepts offers, with 60+ photos and a walkaround video.

Recent 383 R/T sales on BaT and Mecum ran from about $61,600 for drivers to $90,200 for sharper cars. That puts this one well below the market.

What to check

• Ask for the fender tag and broadcast sheet, and confirm the engine and transmission are original or at least correct; the listing does not say
• Mileage conflicts (44,810 vs 12,345 on the dealer page); assume it is unknown
• E-body rust: rear wheelhouses, quarter-panel lower edges, trunk floor and drop-offs, cowl and windshield channel, and floor pans under the carpet
• Check the frame rails and torsion-bar crossmember for rust and old repairs
• Sold as-is with no warranty; get an independent inspection or a live video, and confirm a clean title in hand

Making it drive like new

For a driver R/T, the usual path is upgraded torsion bars and a sway bar, a front disc-brake conversion, a TorqueFlite overdrive swap or a gear change for the highway, and an aluminum radiator. Keep the original parts if you ever want to return it to stock.
