what's the difference between the gmc 100 and chevy 3100?

Question

Accepted Answer

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!

## Key Differences

**1. Brand Identity & Trim**
- **Chevy 3100**: Marketed as the workhorse/entry-level option, with horizontal bar grilles and bowtie badging
- **GMC 100**: Positioned slightly more upscale toward commercial/professional buyers, with GMC-specific grilles and branding

**2. Model Designation System**
In 1953, these trucks used different numbering:
- **Chevy**: 3100 (1/2 ton short bed), 3200 (1/2 ton long bed), 3600 (3/4 ton)
- **GMC**: 100 (1/2 ton), 150 (1/2 ton long bed), 250 (3/4 ton)

**3. Styling**
- **Grille**: Chevy had horizontal bars; GMC had a different pattern
- **Hood emblems**: Different branding
- **Interior trim**: GMC often featured slightly upgraded materials

**4. Production Numbers**
Chevy vastly outsold GMC—so GMC 100s are scarcer today, which some collectors prefer.

## Market Comparison

Based on Classic.com data for the [Chevy Advance Design](https://classic.com/m/chevrolet/advance-design/) market:
- **Average price**: Around $48,500
- **Range**: From ~$450 (project trucks) to over $1.1M (rare highly-optioned examples)
- **Availability**: 98 currently for sale across the entire series

Your [1953 GMC 100 at $49,000](https://classic.com/veh/1953-gmc-100-10122c14431-W9BkZPp/) 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.
