Centerline International

What Centerline International does

Centerline International, founded in 1978 and headquartered at 1450 Overlook Drive in Lafayette, Colorado, is a privately held specialty distributor and e-commerce retailer focused exclusively on Alfa Romeo parts and accessories. The company operates a direct-to-consumer online storefront at centerlinealfa.com supplemented by phone ordering during weekday business hours, and positions itself as the largest Alfa Romeo parts supplier in North America. Inventory spans vintage models (Giulietta, 101 Giulia, Giulia Ti/Super, GTV, Berlina, Spider/Duetto, Alfetta, GTV/6, Milano, 164) and current models (4C, Giulia, Stelvio, Tonale), covering roughly five decades of Alfa Romeo production across performance, restoration, maintenance, and accessories categories.

The core technology and sourcing model combines imported OEM and aftermarket parts from Italy, Europe, and the UK with proprietary components manufactured to Centerline's specifications through a network of local Colorado aerospace fabricators when critical parts are unavailable. This includes exclusive-engineering items such as Colombo and Bariani performance camshafts, Weber carburetor conversion kits, Centerline-exclusive Wilwood 4-piston brake upgrade kits, Magnaflow stainless exhaust systems, and complete engine rebuild component suites (pistons, liners, cylinder heads, gasket sets). A MY CENTERLINE customer account portal supports saved checkout profiles, order history, tracking, return authorization, and access to discounts. The company ships globally on a daily basis, with most orders fulfilled directly from its Lafayette warehouse rather than via overseas drop-ship, which is positioned as a structural advantage versus competitors who rely on import-based fulfillment.

The revenue model is straightforward retail and wholesale parts sales at unit prices ranging from $4.95 (accessories/emblems) to $6,500 (engine/transmission assemblies). Distribution channels include the e-commerce storefront (primary), phone-based inside sales during Mountain Time business hours, and wholesale accounts supplying other parts resellers. The customer base comprises two primary persona segments — classic Alfa Romeo restoration enthusiasts and modern Alfa Romeo owners — plus a secondary B2B segment of other parts suppliers. Headcount is reported at 1-10 employees, and no external funding, institutional investors, M&A activity, partnerships, patents, regulatory actions, or senior leadership hires are disclosed in the source data, leaving the business as a founder-operated specialty e-commerce retailer with a long operating history.

Regional players

• MadAboutAlfa: UK-based Alfa Romeo enthusiast parts and accessories retailer. Comparable product positioning, similar DTC model, but operates primarily in the UK / European market.
