Lot 8595A: 1970 Plymouth GTX

Based on my analysis of recent comparable sales and listings, a 1970 Plymouth GTX is currently worth between $55,000 and $160,000, with most well-maintained examples trading in the $85,000–$105,000 range.

Here’s what drives that value:

🔧 Transmission matters — The manual 4-speed cars like the one you’re looking at typically command a premium. Recent manual GTXs listed or sold from $67K–$160K, with similar-condition automatics generally trading a bit lower (~$55K–$90K).

📊 Recent market activity I found:

• $66,900 – 1970 GTX manual, original condition (currently available, GR Auto Gallery)
• $88,000 – 1970 GTX manual, sold at Mecum Kissimmee auction (Jan 2026)
• $95,700 – 1970 GTX automatic, sold at Mecum Kissimmee auction (Jan 2026)
• $159,900 – High-end 1970 GTX manual with exceptional provenance

🎨 Your specific car — The purple 1970 GTX you’re viewing (VIN RS23UOG240912) at Unique Classic Cars is described as an “Original & Highly Original” 440 4-barrel car with the desirable 4-speed manual. With indicated low miles (1,126) and original condition, it would likely position in the $85K–$110K range based on comparable sales, though the dealer hasn’t published an asking price yet.
