Overview

A red, Fiat 1100-powered, Bertone-bodied Siata 300BC whose identity was only pinned down in 2020, and which was then rebuilt from the ground up over some 3,000 hours by Dutch restorer Martin Dijkhof — the finished car being photographed in 2022, road-tested for Octane in 2023, and sold in December 2025 to a new owner in Monte-Carlo.

History

ST 414BC is an early-series spider with small brakes and, "probably," a Crosley engine when new — the specification of most of the first thirty cars in the series, which left Turin without engines. The Fiat 1100 the car carries today was therefore very likely fitted in America, though it was already in place by the time the car's first documented owner is recorded and it is treated as period-correct by later sources.

ST 414BC's known history begins in the United States with an unidentified owner "possibly [in the] Philadelphia area" — a detail recorded independently by the registry, in both cases tracing back to what Tom Bauder himself said. The car then passed to the Bauder family of New Jersey: **Thomas M. Bauder of Voorhees**, a former US Air Force pilot, and subsequently Tom Bauder. In **2004** it was sold to **Daniel Rapley**, who photographed it at the Bauder home — including images of the car's numbers — before selling it on to **Alessandro Bruni** in Italy.

In **2007** the car went to **Marcel Lammeree** in the Netherlands, and it was first registered there on 30 November 2007 under plate AM4591. Lammeree campaigned it in historic events, entering "Le Mitiche di Bassano" in **2012** with Van Beysterveldt alongside — the Bassano appearance named on the live registry page. At that period the car's identity was uncertain even to the registry.

The car passed to **Renaat Declerck** in Belgium in **2013**, and in **2016** to **Martin Dijkhof** of Dijkhof Autorestauraties in Achterveld, Netherlands. Over the following years Dijkhof and his team carried out a complete, ground-up, nut-and-bolt restoration — some 3,000 hours, much of it done by Martin Dijkhof himself in his spare time — retaining the period-correct Fiat 1100 engine and overhauling the entire drivetrain. The finished car was professionally photographed in May 2022 and the images shared with the registry.

Following the restoration the car was offered for sale from the Netherlands — first through a friend of the restorer approaching the registry directly in May 2022, then through the Dutch trade, listed by dealer DTM Collectibles as a "Siata 300 BC Sport Spider Barchetta" in "Rosso Competizione" with a "Cognac" interior and described as Mille Miglia eligible, and advertised on ClassicCars-ForSale. In March 2023, Dutch magazine Octane published a driving feature on the car, detailing its tuned Fiat 1100 (twin Webers, estimated 50–60 hp), drum brakes all round and Borrani wire wheels, and comparing its handling favourably with a contemporary Ferrari 500 Mondial. The car was still unsold as of late 2023.

In **December 2025** Martin Dijkhof sold the car to **Robert Hilekes**, who lives in **Monte-Carlo, Monaco**. Its first outing under the new ownership came six months later, at the **classic car days of the Yacht Club of Monaco in June 2026**. Its owners describe it as being in perfect condition and report that it now carries a new Monaco registration.
