In October 1955 a facelift model with deeper front and rear screens was introduced. The balanced drop windows were replaced by ones with proper winding mechanisms, there were interior trim improvements, separate amber rear flasher lights and windscreen washers became standard. A new chrome plated grille with fewer vertical slats replaced the earlier diecast version. This model was assembled in New Zealand, alongside the Wyvern and Velox, with 840 being built in 1956, according to a local owners' group with access to copies of the GM Petone plant ledgers. More changes were made in October 1956, with a new grille with horizontal bars, higher compression ratio engine, electrically operated windscreen wipers (replacing the camshaft driven system) and changes to the body trim and two tone colour scheme. In June 1957 the Cresta received a redesigned engine of the same capacity based on the deeper block design introduced in four-cylinder form in the Victor F series in March of that year.
