The journey, Drive 4 Hearts, doubled as a fundraiser for the University of Auckland's Centre for Heart Research, which Prof Paton directs. On Monday, the vehicle — just the 20th ever made — arrived on Parliament grounds, reflecting a 1948 demonstration where it scaled Parliament’s steps to prove its 4WD capability.
