what’s the difference between the gmc 100 and chevy 3100?
The 1953 GMC 100 and Chevy 3100 are actually mechanical twins—they share the same chassis, engines, transmissions, and body from the Advance Design (Chevy) / New Design (GMC) series that ran from 1947-1955. Think of them as the same truck wearing different badges!
1. Brand Identity & Trim
2. Model Designation System In 1953, these trucks used different numbering:
3. Styling
4. Production Numbers Chevy vastly outsold GMC—so GMC 100s are scarcer today, which some collectors prefer.
Based on Classic.com data for the Chevy Advance Design market:
Your 1953 GMC 100 at $49,000 sits right at market average for a custom restomod. With its 350 V8, air ride, and modern comfort upgrades, it’s really punching above what an original-spec truck would cost—which is typical for “restomod” builds in both camps.
