Original Parts Group, Inc.

What Original Parts Group, Inc. does

Original Parts Group, Inc. (OPGI) is a privately held, founder-led specialty retailer and distributor of restoration, aftermarket, and performance parts for classic General Motors vehicles, organized by brand and model line (Chevelle, El Camino, Monte Carlo, GTO, Cutlass, Skylark, Cadillac, GM Trucks, and others) and covering model years from 1936 through 2023. Founded around 1981 and operated continuously for over four decades, the company is headquartered in a 130,000-square-foot facility at 1770 Saturn Way, Seal Beach, California, which combines a retail showroom, inventory warehouse, and shipping center under one roof.

The core product surface is a single e-commerce catalog at opgi.com, segmented into Interior, Exterior, Body Parts & Trim, Suspension & Brakes, Engine & Drivetrain, Audio & Mobile Electronics, and Tools & Car Care, supplemented by eleven full-color printed and digital catalogs organized by GM vehicle segment and a private-label 'Performance by OPGI' sub-brand. The technology layer is conventional — a secure e-commerce platform with SSL/PCI-compliant checkout, inventory and backorder tracking, and a customer-account system with vehicle 'garage' profiles — and the business sells to individual classic-car enthusiasts and professional restorers rather than to enterprise accounts.

OPGI runs a direct-to-consumer go-to-market across five ordering channels: opgi.com (24/7), toll-free phone, fax, mail, and walk-in showroom. Pricing is one-time transaction-based with a $299 free-ground-shipping threshold (contiguous US), Affirm financing for orders above $400, COD allowed up to $899, plus volume discounts, a frequent-buyer points program, a price-match guarantee, and 'Kit Swap' savings for restoration bundlers. Marketing relies on catalog distribution, an opt-in email newsletter, organic/SEO on opgi.com, and recurring TV presence on enthusiast automotive programs including Mecum Auctions, Barrett-Jackson, Sam's Garage, Bitchin' Rides, and Detroit Muscle.
