Before Hendrik-Jan Spijker's death, he and his brother had developed a special relationship with Dutch electrical pioneer, [[:nl:Rento Hofstede Crull|Rento Hofstede Crull]].<ref>[[:nl:Rento Hofstede Crull]]</ref>  The Spijker brothers had known Hofstede Crull already when he was a young man racing on the velocipede circuits in the Netherlands and in Germany while he was an engineering student first in Mittweida and later in Hannover at the Technische Hochschule in the 1880s.  Hofstede Crull had already owned his first automobile in the 1890s.  In the first decade, he had accumulated a collection of automobiles which included a number of the Spijker racing models.  He housed the collection in one of the wings of the [[:nl:Heemaf|Heemaf]],<ref>[[:nl:Heemaf]]</ref> one of the companies he had founded.  Although this was all a hobby for him initially, he began assembling Spijkers at Heemaf with the approval of the Spijker brothers and subsequently with that of those who had taken over Spijker.  He provided them with improvements on the automobiles.  Heemaf's board of directors<ref>Heemaf was a public-traded company</ref> complained that Hofstede Crull was using a part of the factory as his personal garage and auto park.  To circumvent the criticism, he established the ''Spijker Automobiel Verhuur Maatschappij'' which along with Amsterdam's ''Trompenburg Bedrijf'' became the first auto rental companies in the Netherlands.<ref>Jaap Tuik.

This all stemmed from an automobile accident that he, Hofstede Crull, and his chauffeur, a man named Poorthuis, had in 1909 when he subsequently discovered a defect in the Spijker's steering mechanism<ref>{{Cite web|url=http://www.holechistorie.nl/index.php?option=com_content&view=article&id=204:auto-o...|title = Holechistorie.nl}}</ref> which he improved.
